With the beginning of the new year, questions like ‘is the (insert the right technology here) still good in 2022, should I learn (said technology) in 2022’ etc. arise once again. This article will focus on React, since many people are concerned whether Angular and Vue.js are not overshadowing the Facebook framework. Here are some arguments ‘for’ using React.js in 2022.

## A quick recap of React.js

React is known as a free, open-source and declarative front-end JavaScript library, providing great flexibilty and efficiency to its users. React is used for developing UI-component based user interaces. It was first created by a Facebok developer and dedicated to complex web interfaces as well as single-page applications. According to many developer surveys, React continues to be the main choice of software engineers, while being users by huge enterprises like Instagram, Netflix or Apple.

## Reasons to choose React in 2022

There are plenty of resons why you should choose React in 2022, so let’s look at them together.

### 1. React Github contributors

The number of contributors on[ Github](https://github.com/facebook/react) often is a good factor to consider whether the framework, library or programming language is going strong in the community. React.js still has over 1500 contributors with nearly 15 000 commits. It means that this JavaScript library is alive and well and is constantly improved giving the developers a wide variety of actions available for solving certain problems.

### 2. Library flexibility

Among many advantages of using React.js, flexibility is the one that is frequently mentioned. Due to its component-based architecture, the library is user-friendly and allows a high level of modularity. React’s codebase is lightweight, easy to maintain and parts of migration between versions can be done automatically, thanks to the[ react-codemod](https://github.com/reactjs/react-codemod) tool developed by people from React core team.

### 3. SEO integration

Search Engine Optimization is a process used by companies to increase user traffic. By using SSR (Server Side Rendering) you can achieve low TTI (Time to Interactive). After the app is loaded, React uses optimized algorithms to ensure it works as fast as it loads. This means, more users are able to browse the site, which in return, should result in bigger revenue.

### 4. React is easy to learn

React community is one of the biggest amongst other frontend frameworks. Because of that, there is plenty of tutorials, materials, and already answered questions on forums like[ StackOverflow](https://stackoverflow.com/questions/tagged/reactjs). This, together with React’s improved documentation (much better than in 2017) gives newcomers an easy way to master the library in 2022. On top of that, knowledge of HTML and JavaScript gives the advantage to learn React even faster. Another year of React’s strong presence on the market means there are more experienced developers, best practices are continuing to crystallize and the overall quality of React apps goes up. This gives an advantage to product owners, as well as new developers, who can learn from experts.

### 5. Virtual DOM

React is known for its virtual[ DOM](https://reactjs.org/docs/faq-internals.html) (Document Object Model) which allows updating only the parts of the webpage that were changed after user interaction. This has a huge impact on performance improvements, as operations on actual browser DOM are expensive. That way, by making operations first on the Virtual DOM, React is able to omit operations on the DOM elements that remained the same. This is extra important in bigger applications, where we need to squeeze all the performance so the users can have a fluid experience even when loads number of data is displayed on the screen.

### 6. React JSX

React introduced a syntax extension for JavaScript called[ JSX](https://reactjs.org/docs/introducing-jsx.html). It is an HTML-like syntax that is transpiled to regular JavaScript and then builds a Virtual DOM mentioned earlier. Even though the decision to keep "HTML" inside JS has met mixed opinions amongst developers, it seems to be surviving the trial of time and proves itself on many commercial applications.

### 7. Library maturity

Despite being 10 years old, React is still doing well in the fast-paced world of JavaScript frameworks/libraries. All this time, we have been spectating React going from “yet another JS framework” to being at the forefront of the market. As for 2022, we are still waiting for multiple new features to be incorporated into React. What is more, the past years lead to having many ready-to-use open source packages for common use cases thanks to the active community gathered around the framework.

## Summary

Those are just a couple of reasons behind why you should continue or start using React in 2022, but there is obviously more of them. React JSX, virtual DOM and flexibility alone are the key features that prove that it is an amazing choice and despite the ever-present comparisons to frameworks like Angular or Vue, the React community remains intact.

Are you wondering if React is a good fit for you in 2022? Read this article to find out.

Is React A Good Pick For 2022?

If you’re looking to build websites or mobile apps, you need to look no further than React.js (sometimes known as Reactjs or simply React). 

React is an open-source Javascript library that’s used for handling the front-end development of some of the best web and mobile applications, including those of some of the top **FTSE100 companies**.

In fact, Stack Overflow’s 2020 Development Survey showed that [68.9%](https://www.thinslices.com/blog/infographic-react.js-statistics) of nearly 60,000 respondents claimed that they wanted to continue to work with React, the second best figure of the whole survey.

Wondering what the big deal about React.js is? Read on to find out why you should choose Reactjs instead of other programming languages, and pick up some top tips on how to find the top Reactjs developers.

## Why You Should Use ReactJS For Web Development

On August 31st 2020, LinkedIn Jobs boasted far more jobs for software developers than Vue and Angular combined - nearly [50,000](https://www.thinslices.com/blog/infographic-react.js-statistics) were available.

But the wider talent pool available when it comes to hiring a [React.js developer](https://selleo.com/react-expert-developers-team) is just one of many reasons that React.js is the go-to for building web apps right now. Here are the top 10 reasons why you should choose Reactjs for web development:

### Top 9 Benefits of ReactJS

![Img](https://a.storyblok.com/f/86602/720x396/3afcba94a2/top-9-benefits-of-reactjs.jpeg)

1. **Flexibility:** React, in contrast to other front-end frameworks, by itself provides simple tools for building web applications. Depending on your needs, additional functionalities can be bolted on in the form of open-source packages. This approach allows programmers to choose from dozens of alternatives and custom tailor the application to any needs.
2. **Faster rendering:** it is designed to be fast by default but additional performance improvements can be done in mission-critical areas. This allows SPA’s created in React to respond swiftly to user interactions and rapid development.
3. **Stable code:** React codebase is carefully designed, so changes are backwards compatible. There are also additional tools helping React developers with migration to the newer versions as well as those helping to follow the best practices.
4. **SEO friendly:** If having good SEO is your priority, React paired with tools like Next.js or Gatsby can provide good results in page load speed and fluent user experience after the application is loaded.
5. **Helpful tools:** thanks to React development tools engineers can dive into the application internals while it is running, allowing them to find potential or existing issues. This leads to fewer bugs and quicker fixing time.
6. **React Native:** any developer familiar with React, is also familiar with React Native as they both are based on similar principles. It’s only a matter of getting accustomed to a few differences in the web and mobile world, and they (React developers) are ready to go. This is really a superpower no other frontend framework can provide, that the same developers can create web, native apps for both iOS and Android devices.
7. **Easy to learn:** React closely resembles using regular JS and HTML. It is based on a few core concepts and compared to other frameworks has a small surface area for the developers to learn. This makes it really easy to pick up by any programmer knowing JS and HTML.
8. **Big community:** The open-source nature of React means that a lot of problems are already solved by other developers and the solutions are available to be reused in a form of open-source packages. Any React developer can quickly pick up those packages and use them in their project, saving time in the development process and therefore development costs.
9. **Used by many successful enterprises:** if there was one sure-fire way to prove that React is the real deal, it’s that some of the biggest companies in the world use it for their own React applications. Try **Facebook, Netflix or DropBox** for example.

<Baner name={react} />

### **What Types of Applications Feature React?**

Speaking of popular uses of React.js, let’s check out some of the most popular types of web applications that use it. React is particularly useful for, but not limited to, the following:

* **Single page applications:** some examples of popular SPAs that have been built using React are **Facebook, Github, Twitter and Gmail**.
* **Dynamic web applications:** more dynamic apps used to be incredibly complicated to develop because of some immensely long lines of code, but React makes it a whole lot easier by breaking down the process into much more accessible chunks.
* **Complex user interfaces:** again, React breaks up really complicated UI into individual components that are much easier to navigate and handle for the developers working on them.

## 10 Reasons to outsource React development

So, it’s pretty clear that React just about has it all. There is a whole tonne of major advantages for using it, including mobile app development with React Native.

In order to save time and still get the best out of React.js you should look into outsourcing the development instead of hiring an in-house team.

Here are 10 fantastic reasons to hire dedicated React developers and outsource your product creation:

![Img](https://a.storyblok.com/f/86602/720x429/b502800bdd/10-reasons-to-outsource-react-development-2.jpg)

 1. **Cost-efficiency -** remember, time is money. So, any time saved is money saved. The guys who offer React.js software development services for a living will likely turn around their work quicker than an in-house team, which is something to take advantage of.
 2. **Maintain focus on business processes -** something to do with that time saved is sticking to the business plan. You don't have to be distracted by the actual development - just pitch an idea and have it come to life.
 3. **The best quality -** perhaps most importantly of all is the overall quality of the product. The user experience is key to generating revenue, so you're going to want the best of the best. This can come from outsourcing, because software houses have internal practices and standards developed through multiple different projects and shared between their employees.
 4. **Easy to maintain -** rather than the hassle of hiring and maintaining a whole in-house team to look after your web application, when outsourcing the creation of your product to fully managed teams you only need to care about the B2B relationship with the contractor company.
 5. **Scalable -** as your business grows, it's important to make sure that your applications grow with it. Another drawback of an in-house, non-specialist team is that this growth will take longer, as finding skilled developers takes a lot of time, while outsourcing companies already have a pool of talents who went through the hiring process.
 6. **Less paperwork -** hiring permanent or even temporary staff requires a lot of paperwork which, again, is time-consuming and just does not need to happen. Outsourcing React.js can be incredibly quick, as it's just a matter of selecting a subcontractor.
 7. **Tax benefits -** here's something that a lot of people don't consider about React.js outsourcing. The amount of taxes that you will need to pay to members of your staff in an in-house team can become very high, very quickly. With outsourcing, all you need to pay is VAT.
 8. **Time-to-market -** when you launch your web application or any update to it, you're going to want to get it out there as quickly as possible so that your current or potential new customers can see it sooner. Outsourcing can speed things up significantly.
 9. **Fresh perspective -** instead of the same people looking over the product to try and find new methods of innovation within it, a fresh set of eyes from an outsourced team should help to get things feeling fresh again.
10. **Access to a wide talent pool -** and last, but of course by no means least, it comes back to that wide talent pool of quality developers that are out there. This could be the difference between a standard web app or an incredible one.

## How to choose the right [ReactJS development company](https://selleo.com/react-expert-developers-team)?

Any React specialists team should be able to fulfill all of the criteria just listed and then some. To find out if the team that you have your eyes on does this, there are a few things that you can look out for when hiring developers.

![Img](https://a.storyblok.com/f/86602/720x363/38b2ef653f/how-to-choose-the-right-reactjs-development-company.jpg)

If you see all of the following items on the website of a potential development team, and they are all presented convincingly, you may well be on the right track to finding the expertise you need to get the best out of React.js:

1. **A portfolio of their work:** any team worth their salt should be proud of the work they have completed to date. For this reason, you should be able to see a whole bunch of their work on their website. Anything other than this is a red flag!
2. **Testimonials from previous or current clients:** the clients that the development company has worked with should also be proud of that company’s work. There should be plenty of positive comments from previous customers being shown off on the website, too.
3. **LinkedIn recommendations:** head over to the LinkedIn page of the development company for a purer, unfiltered look at what people really think of them. You’d be able to see negative comments here, too, and these would usually not be seen on the company’s actual website.

Overall client satisfaction: to go one step further, you could check out even more independent review sites such as Google reviews or Trustpilot to make 100% sure that you are not having the wool pulled over your eyes.

### What Skills should a React.js Developer have?

Once you have had a good look at a potential development company to work with, it’s time to find out whether they have a good development team with React in their tech stack.

To check to find out whether you got yourself a good React developer or not, run them through these criteria before you even think about taking them on for an interview:

1. **Knowledge of testing:** it may seem obvious to read it now, but you would be surprised how often the testing phase of web application development is overlooked or rushed. This can cause all sorts of problems later down the line.
2. **Knowledge of various architectural patterns:** knowing all about React is one thing, but understanding the different architectural patterns that work alongside it is another.
3. **Understanding of other technologies:** it’s a nice-to-have if a developer has worked with other Javascript library programmes such as Angular or Vue, then they will have a better scope of React’s worth and therefore would be better at using it.
4. **Fluency with pure Javascript:** Javascript in its purest form is the basics and if a developer can show an understanding of it, this is a good sign that they will be skilled at React, a Javascript library.

### **Top Interview Questions to [Hire a React Developer](https://selleo.com/react-expert-developers-team)**

![Img](https://a.storyblok.com/f/86602/720x363/79de10cbc2/top-interview-questions-to-hire-a-reactjs-developer.jpg)

The interview stage is a crucial part of the whole development process of your web application because this is where you decide who is going to be in charge of bringing it to life.

To help with this, we’ve put together some questions that you can use in your own interviews. While these set out a good pathway, it’s also important to add in some questions that are specific and unique to the project you are about to embark on.

1. **How can you create an event in React?** That’s a really trivial question, but the fluency of the answer might show if asked developers are confident of their skills.
2. **Can you tell why the introduction of React hooks was a game-changer?** Any developer in modern times should know that, as hooks changed a lot regarding how applications are now written and designed.
3. **What do you like most about React?** Does this developer's taste align with your own?
4. **What's the most difficult performance issue you've ever fixed with React.js?** When the software engineer inevitably runs into performance problems at some point, you need to know how good they are at digging themselves out of them.
5. **What is the difference between controlled and uncontrolled components in React?** Another important question if your application is going to have big/complex forms.
6. **What are the downsides of React?** Does this developer understand what the drawbacks are and how to overcome or get around them?
7. **What's the difference between Real and Virtual DOM?** This is a unique and core feature of React, so your candidates should know it.
8. **What's the difference between pure components and general components in React?** To squeeze the most from React performance your candidate need to know the difference between these two.

How would you create Higher Order Components (HOC) in React? Currently, there are new ways to share common behaviour in your application, but if your React.js developers know about HOC’s it means they have at least a few years of experience in the technology.

Outsourcing ReactJS Development Services | Learn How To Do It Right

\[TOC\]

The automation of business processes is increasing rapidly with huge corporate needs. To manage every department of an organization, every process of manufacturing to supply chain and every employee in-house, every activity from payroll to marketing, an organization needs an **Intelligent System**. The technological advancement has presented a solution in the form of **Business Intelligence**. It is a technology-driven solution to analyze data, deliver actionable information that helps executives, managers and workers make informed business decisions.

A **BI helps make marketing, sales and customer service more efficient and effective**. It helps to speed up the decision-making process by identifying ever-changing business and market trends. It also helps **optimize internal business processes, increases operational efficiency and drives higher sales and revenues**.

One of the main focuses of BI is to provide everything in one place, which is called a ‘Dashboard.’ In this article, we will learn **how to build a useful Business Intelligence Dashboard**.

First, we will learn more about a BI Dashboard and why a business needs one.

## What is BI Dashboard and Why Do You Need One?

A BI Dashboard is an **information management solution** that helps to design and track KPIs of the business and employees, metrics and other useful information related to a business, department, or specific process. By gathering all the data, a BI dashboard helps to **visualize and simplify complex data** sets to provide users with at a glance awareness of business, department or individual performance.

For businesses having a lot of data is always a hassle, but if the data is logically grouped, sorted and filtered, then it can help businesses to make a firm and sound decision more quickly. The data should also be easily accessible and maintainable. The entire job of gathering, sorting, filtering and grouping the data is done by BI dashboard.

Now, you would be wondering if there are different kinds of BI Dashboard. Well, yes, there are different types of BI Dashboard as per client needs and requirements. These types are:

1. Operational Dashboard
2. Analytical Dashboard

### What is an Operational Dashboard?

A dashboard which is designed to monitor frequently changing business processes and track performance of key metrics and KPIs is called ‘Operational Dashboard.’

Unlike other types of BI Dashboards, an **Operational Dashboard is designed to record and monitor data updates** on a very frequent basis. In some cases, the data changes or is updated in minutes. The Operational Dashboards are viewed by executives and managers many times throughout the day. Usually, the Operational Dashboard monitors the progress towards a specific target.

One of the most common examples of an Operational Dashboard is a ‘Daily Web Overview.’ It tracks hourly web performance against predetermined objectives for a digital marketing team.

### What is an Analytical Dashboard?

A dashboard designed to **analyze a massive amount of data and allow its users to investigate the trends, predict outcomes and monitor insights** is called an ‘Analytical Dashboard.’

The Analytical Dashboard is very common **reporting tool** as it is designed to perform very basic analysis and designed by data analysts. The data on Analytical Dashboard collected infrequently, and it should be 100% accurate and up-to-date. These dashboards also offer advanced BI features like **drill-down and ad-hoc querying**.

One of the most common examples of an Analytical Dashboard is MRR/Accounts.

Not all Business Intelligence Dashboards can be trusted. Let’s have a look at some of the factors which make a BI Dashboard more effective.

## What Makes A Business Intelligence Dashboard Effective & Useful?

The purpose of a BI Dashboard is to **simplify a detailed analysis of huge amounts of data** to avoid missing any trend or pattern. A useful BI Dashboard can provide graphs, charts, and other meaningful and presentable visualization instruments to empower a team or department to interpret the data and transform it into actionable insights that will benefit the organization in many ways. Apart from visualization, many other factors matter a lot. These factors are:

### Real-Time Access to Key Metrics

BI Dashboard is mainly focused on tracking **KPIs and Key metrics** for a specific target or the entire organization’s goals. With real-time access to the key metrics, it is easy to amend the strategies to meet targets more quickly than expected.

### Trend Identifications

BI Dashboards helps businesses across different sectors to identify and analyze changing trends. It empowers the business to respond to positive trends related to a wealth of business activities while isolating and correcting negative trends for improved organizational efficiency.

### Quick Fixes

A useful BI Dashboard must have the **flexibility and freedom** to monitor derivations, analyze them, and fix the issues quickly without giving any command in the programming. It should be designed to make small fixes itself.

### Overall Performance

A BI Dashboard should have the ability to observe departments, employees, and company performance on both the individual level and overall performance basis.

### Real-Time Tracking

A BI Dashboard should have the ability to track **time-sensitive actions** and target progress frequently.

### Analytical Approach

A useful BI Dashboard is designed to find a weak point in the company management system and notify the management.

What features a BI Dashboard should provide to its users? Let’s discover them.

<Baner name={react} />

## The list of Must-Have Features

The most important BI Dashboard features include:

### Customizable Interface

A BI Dashboard interface should be customizable to be mould as per the team and department needs. The customization is also important for the type of data collecting over the dashboard.

### Interactivity

Interactivity is one of the most important features of a BI Dashboard. Interactive reports help executives and managers to condense the vast data into a wide variety of views. Through interactivity, users can take advantage of statistical analysis and regression to identify trends, anomalies, and outliers in the data.

### Ability to Pull Near Real-Time Data

The data on the BI Dashboard updated frequently, and this feature makes it possible for the organization to pull near real-time information anytime.

### Real-Time Monitoring of Key Metrics

Another most important feature of a BI Dashboard is **real-time monitoring of Key metrics** by providing an at-a-glance view of pertinent data and analytics with visualization. Areas where urgent attention is required to become ‘Call-to-Actions.’

### Single View of the Truth

Single View of the Truth (SVOT) is a concept of having a centralized database. It is better than a diffused system where data are kept in multiple databases or files. A centralized database helps organizations to integrate all channels, including sales, CRM, warehouse, inventory, and supply chain, via a single system.

### Ranking Reports

A BI Dashboard allows you to generate reports to learn about your business's best- and worst-performing facets. These ranking reports help companies to view rankings across multiple dimensions and specify various criteria to focus your results.

### Flexibility

A BI Dashboard provides complete flexibility and freedom to view trends, performance, and track metrics 24/7 from anywhere. You cannot provide admin rights to every team member. Therefore a BI dashboard should be flexible and aligned for different departments and user levels such as managers, executives, and analysts.

### Identifying Goals

A BI Dashboard can work on different key metrics. A user must identify the goals before starting creating metrics. You should know your target audience, what kind of data you will pull in, who will have access to this data, and what level. Every question should be answered correctly.

### Solving Business Problems

The reports generated by the BI dashboard should be problem-solving oriented. The dashboard should be flexible to adjust and customize based on user type.

### Attractive & Simple UI/UX

The UI/UX should be detailed and straightforward at the same time. Clutter should be avoided because less is better when it comes to the analysis of massive data. Don’t pack too many visual elements into one dashboard.

## How to Build BI in React?

React is a super-fast JavaScript library. It allows for creating modular and interactive UIs. React efficiently update and render components whenever data changes. This makes it a perfect choice for real-time data visualization.

React works exceptionally well with common data visualization libraries such as d3 or high charts.

### Our Case Study

Selleo has recently worked with [Accelerated Digital Ventures](https://accelerated.ventures/) – a UK UK-based company to create a platform that sits at the heart of the venture ecosystem connecting leading early-stage companies with funds like **Seedcamp, Episode1, or Techstars.** ADV has managed to help 54 companies operating in 13 business sectors, mostly in a Pre-Seed, Seed, or Seed Extension stage.

ADV's mission is to increase the flow of investor capital to the back of the startups. They aimed to connect top 20% institutional investors with leading 20% tech companies. To make it happen, ADV wanted to develop an environment that would serve that purpose and improve their business processes.

The ecosystem should serve the needs of:

* Leading tech companies who are ready and motivated to pursue their long-term ambitions
* Early-stage investors looking for capital supply
* large institutional investors by enabling them to engage with the early-stage venture ecosystem
* Accelerated Digital Ventures itself by optimizing their business processes, making them more comfortable, practical, and less time-consuming

To support ADV's vision, two platforms were built.

The Business Connect platform provides a complete environment for startups and investors to establish connections between those parties. Notable features that were implemented include:

* Tracking time-sensitive actions
* Tracking every step of a multi-step procedure
* Allow collaboration between experts
* Managing the company’s portfolio
* Generating reports to track company performance
* Feedback sharing

How To Build An Effective Business Intelligence Dashboard In React?

\[TOC\]

Even in 2020, React.js and React Native still remain ones of the **most popular frameworks for [front-end development](https://selleo.com/custom-software-development-company)**. Thanks to its declarative nature, React is used to build interactive user interfaces with great ease and flexibility as well as easy updating and rendering of components.

Because React is constantly providing developers with good work experiences and the advantage to change any component at any point, every year there are new React engineers on the market.

If you are currently **looking to hire the best React software engineer**, this article is for you. I will also share my story of how I become one. Let's discuss together how to hire amazing React developers.

## What is React.js and React Native

I want to start with a short introduction of [React](https://pl.reactjs.org/) and[ React Native](https://reactnative.dev/), in case some of you are not familiar with them.

React.js was released in 2013 as **a JavaScript library for building web user interfaces**. Created by Jordan Walke, a software developer working for Facebook, it allows creating apps with large amounts of data and changing this data without page reload.

The main purpose of React.js is to be fast, scalable while remaining simple and giving the developers the ability to create components that can be used as skeletons for applications.

React Native is a framework based on React.js that utilizes its concepts and was created for **building cross-platform mobile apps**. Thanks to that, it allows money savings on human resources. React Native was released in 2015, built on React library that itself is a large ecosystem. It is used by developers to create natively rendered mobile applications for iOS and Android with the usage of JavaScript, using the same codebase for both.

Thanks to React Native, developers that were previously working with web technologies are able to create powerful mobile applications.

## The popularity of React and who uses it?

The popularity of a framework can be easily measured and over time it can show the ongoing trends in the programming community.

According to[ Stackoverflow's 2020 survey](https://insights.stackoverflow.com/survey/2020#technology-most-loved-dreaded-and-wanted-web-frameworks-loved2), React is the first most wanted web framework and the second most loved web framework. If compared to Angular or Vue.js, React is still at the top. What is more, react has over [1 million repositories of GitHub](https://github.com/search?q=react).

## Benefits of using React

Now it is time to discuss the benefits of React.js both from a business owner's perspective as well as a developer's point of view.

### Business perspective

* **popularity -** React is a stable and mature technology that has been gaining popularity throughout the years and is not going anywhere anytime soon.
* **SEO friendly -** not only Facebook loves React, Google does too. Search engines sometimes have trouble reading JavaScript-heavy applications, but it is not the case for React.js.
* **cost-effective -** there is no need to spend money thanks to the shortened time to market
* **great user experience -** thanks to features like Concurrent Mode, virtual DOM or React Fiber, React apps are super fast, positively influencing user experience.
* **performance and speed -** React is known for its speed and amazing performance. If it is good for Netflix and Instagram, it will definitely be good enough for you too.
* **time-to-market -** especially for startups, time-to-market is crucial. By using React for web app development, you can build your product faster, release an MVP for testing and later on make changes accordingly.
* **easy to hire developers -** the stable popularity of the framework means the talent pool of React engineers is growing with the demand for them. It should not be hard to find qualified developers for your project.

### Developer’s perspective

* **Concurrent Mode -** a set of features making React apps fast and user-friendly. It makes them adapt to the user's device capabilities and network speed.
* **backward compatibility -** the public API remains almost the same every year making it easier to refresh the code while using its old pieces.
* **app development time -** with ready-to-use solutions, reusable components and a ‘Create React App' starter kit, React.js is not only fast in load speed, but also the development time.
* **easy to learn -** using React should be easy for any JavaScript-experienced developer
* **Custom React Renderers -** thanks to it you can build custom implementation
* **community -** there is a great chance that the problem you are facing has already been solved by somebody, so it will be easy to find help among other React contributors.
* **modularity -** every component and subcomponent can be reused whenever and wherever. Modularity also means React apps are easy to scale - you can start small and build up from there.<ReadMore> Read also: [How To Build An Effective Business Intelligence Dashboard In React?](https://selleo.com/blog/how-to-build-an-effective-business-intelligence-dashboard-in-react-) </ReadMore>

## How did I become a React Native developer?

Now it is the time to tell my personal story of how I became a React Native developer.

I am a civil engineer by education. I was seeking new job opportunities and challenges to help me grow. After making the decision to rebrand and change my occupation I started researching what technologies were worth learning. **JavaScript** seemed to be a modern language that is quite easy to master while giving you opportunities to build applications in many areas from back-end to front-end, including desktop and native mobile apps.

<Baner name={contact-us} />

My adventure began with learning web development basic principles like **HTML and CSS**. After mastering the fundamental web development knowledge it was time to get familiar with JavaScript and its modern, commonly used version ES6 that provides new syntax. When I finally felt comfortable enough with it, I started looking for a framework that I could use to develop complex applications. After many hours of research, I decided to go with **React** due to its popularity and community resources. When it came to learning React principles and usage of libraries I had run into some problems that were hard for me to understand. At that time I was also looking for a new job and found out that Selleo also accepts people for some kind of internship. My mentor taught me a lot about working with React and its libraries. After joining in full-time I started working with **React Native** to finally join my first React Native project - an app for a fintech company. The application's main goal was to help customers manage their expenses, maintain a credit card balance and store receipts for accounting purposes.

## How to hire React developers?

Let's talk about the main topic of this article now: **how to hire a React.js developer for your project**. There are two ways to go about this, either hire in-house or outsource the development. Of course, there are advantages and disadvantages to both.

The pros of developers hiring in-house are a cultural fit, facet-to-face communication possibilities and quicker changes. However, in-house software development means **higher costs** as you have to take care of expenses like rent, taxes, software and hardware and obviously the salary. What is more, the staff turnover is always more possible as software developers have a tendency to change the working place quite often because of the market's demand. Hiring in-house can also be challenging when it comes to **finding the right talent** and the hiring process.

A perfect solution for the problems with in-house development is **outsourcing**. According to [Statista](https://statista.com/forecasts/967679/it-application-outsourcing-services-revenue-in-the-world), the IT-application outsourcing market is expected to amount to approximately **96.7 billion U.S. Dollars by 2021**. Outsourcing offers great cost flexibility as a lot of companies, like Selleo, that offer those services offer affordable prices. You also gain access to a huge worldwide talent pool with unlimited hiring opportunities. Ease of scalability is also a big advantage. With outsourcing, you can expect a faster project delivery as it reduces the time spent on recruiting.
