A listing of hi-tech development tools keeps growing continuously. Some of these tools better fit your project needs than others, which is extremely clear. For somebody, it will suffice to build a simple frontend using HTML, CSS, and JavaScript. But as the app grows, you might need more powerful tools for creating complex user interfaces — frameworks and libraries. Accordingly, once we deal with such a large and rapidly changing ecosystem, it is extremely important to learn about the exact up-to-date industry trends.

Front-end frameworks and libraries help address common growth problems when building maintainable and modular applications. Comparison of different frameworks and libraries normally comes down to what issues a given framework fails to deal with. In this sense, React is definitely rightly viewed as the most popular front-end library that continues to grow at a much faster rate. In 2020, it has also been adored and”wanted” than any other JavaScript front-end framework or library.

The purpose of this manual is to ascertain why React is favored over other frameworks and libraries, how it can benefit the backend development process, and why choosing a front-end development library for your next project in 2021, you need to go for React.

What is React?

React is a declarative, efficient, and flexible JavaScript library used by applications engineers to build user interfaces. In addition, it goes by the React.jsReactJS, and React JS names used interchangeably. So yes, it’s a library, and if you’ve ever felt confused about if React JS is a library or a framework, now you know the ideal answer.

React is a product of a monumental amount of corporate investment, which sets it apart among its peers. Back in 2011, Facebook created React but hadn’t open-sourced it until May 2013 when the corresponding GitHub repository was set up, together with the library launch was officially announced. By 2014, after React was widely used for growing the UI of Facebook and Instagram and has been analyzed and assessed in the uncontrolled by other developers, the library started to become popular.

The development of React has become the response to problems usually encountered while building JavaScript applications. As apps were growing in size and sophistication, these issues were becoming more nagging. Luckily, the fact that React was created and is heavily used by Facebook to handle their own problems only increases the library’s quality and efficacy in dealing with similar issues faced on other endeavors. The React core team is dedicated to creating positive changes so that they would make the programmer’s life easier.

What is React JS good for?  Fundamentally, React makes it effortless to create interactive user interfaces. It helps building standalone UI components and entire user interfaces, including each the visual elements and the logic that underlies and modulates these components. In the first place, React is made for constructing robust component-centric applications. However, although it’s a hi-tech technology, React is not opinionated and could be paired with a number of different other technologies implementing the backend, too. This way, Reacts functions as a vibrant ecosystem of tools and approaches, which states its having so many different use cases — web app development (where it all started,) mobile app development, static site structure, desktop apps development, and even VR app development. The notion of learning and using it everywhere is not new but still true in the case of React.js.

The strong community is one of React’s very significant advantages, which we will go into more detail later in the report. On the graph below, you can see official information supplied by npm, Inc., the company behind Node program manager, the npm Registry, and npm CLI. The graph showcases download information for React, Vue, and Angular packages in the past five decades.

In Addition, the current Developer study by StackOverflow demonstrated that React.js is the 2nd most loved development library that’s appreciated by 68.9percent of respondents:

When you look at these stats, it becomes evident that the React community is second to none. Regardless of the fact that there are other great alternatives out there in JavaScript, that React is backed by such a monumental community and therefore novices are always able to rely on other more experienced colleagues to help is definitely part of the reason so many women and men are coalescing on this library.

So, who uses React? There’s a tiny chicken-and-egg problem in this question. It’s a lot more likely, but it was the community’s active support and interest in React that has caused a massive number of companies that the vast majority of us have heard of and possibly even respect to start using it.

Now that we’ve defined what React.js is, yet another substantial question arises: Why is this library so prevalent? What are the benefits of React that encourage so many businesses to use it?

Top Benefits of ReactJS for front-end development

If you asked us what hi-tech technology will probably be best suited to applications development in 2021, we would answer, of course, React! It’s on par with Angular regarding rate, development flexibility, and popularity. Vue.js is much more lightweight than its counterparts, but it doesn’t bring significant advantages in real life. Sounds excellent, and yet, there is definitely more in React than that!

Therefore, if you wonder why use React on the following job, we may supply you top notch 7 reasons to conquer your hesitation!

1. ) React has a steep learning curve.

Most developers love React.js as it is efficient, declarative, and flexible. What is even more significant and intriguing is that learning React is far easier than learning other JavaScript frameworks.

Is React easier than Angular? The short answer is: yes. Or rather, it is more likely than not, and there is a fairly simple explanation:

    • React is a library and a comprehensive solution that is built around one main concept, which is to give you more freedom in how you use the library to compose and organize your own personal component-based architecture.
    • Angular, then, is more like a constructor or a tree of components, so you need to comprehend how its elements behave, work, and mix together.

Nevertheless, React’s relative simplicity will not purely depend on its file structure and component model, making the code easier to understand and begin. Obviously, React.js doesn’t burden developers with too many things to be emotionally handled. It generally does have a simpler file tree and elastic component design. But also — and that’s a significant benefit — React will have a much shorter dependency list. While Angular’s dependencies form a dizzying set that’s problematic to track, React aims to make developer’s life easier by considerably shortening the identical lists.

The harder a technology is to learn, the longer it takes to start the development procedure. Therefore, a steep learning curve is among the chief reasons why React has gained so much traction in this short moment. Given React’s simplicity, companies today are more inclined to use it, thus building their tasks faster.

2. ) ReactJS is quite elastic.

Another reason that you will need to use React is its flexibility that manifests itself in several ways. It is especially visible in regards to the use of React for web development. Web development projects often develop into bulky systems that could be challenging to fix or enhance.

First, once we talk about React’s flexibility, we refer to the library’s inherent modularity. React’s architecture allows bundling front-end code into custom components, thus giving a great foundation for the complete development process optimization. The React’s position on the scale of opinionatedness is stable — the library neither protects nor guides you in their own way of doing things. On the one hand, it dictates how you will need to create reusable components. On the other hand, it offers a completely free hand to determine how to handle routing and testing, organize dependencies, and much more. This degree of freedom can turn out confusing for novices but at precisely the exact same time, working in a React development environment is a pure delight for experienced developers. In this manner, React.js enables you to write clean, modular code, dividing the job into various components. As a result of this, when code is modular, it becomes easy to maintain and scale.

Second, React is super flexible in the sense it might be integrated with other third party libraries and MVC frameworks. You can elect to create a React project from scratch or gradually introduce React to your existing legacy codebase. Creating a new React app is not too tricky. Embedding React components one by one into your code composed of unique technologies isn’t a matter, also. And vice-versa — it’s relatively straightforward to integrate third party libraries to React applications.

So, using React for front-end is a exceptional option! In any case, while we are on the topic of flexibility, it has to be noted that another significant advantage is the ease of transfer and support of React Native apps. It is a framework for constructing native apps using React, so if you happen to know how to build apps using React, you are already well on your way to getting well-versed in React Native, too. They are conceptually similar. The Vast Majority of the React theories move to React Native. For this reason, you can waste no time, learn React Native, and start developing mobile apps for iOS and Android with a native look and feel.

3. React.js offers quick representation.

React is a client-side JavaScript library that uses server-side rendering. Why is it a benefit? Greater support for server-side rendering turns directly into a robust performance-oriented solution perfect for generating content-focused applications, be it a web app or native-rendered apps for Android and iOS.

React has everything for a brilliant performance. Faster rendering has a massive impact on reducing load times and quickly adapting the operation in real-time based on user traffic flow. It’s common knowledge that the faster the page load speed, the more customers won’t leave the website and will use your service or purchase your goods. This is very important for companies operating online.

React’s Virtual DOM is basically the prime cause of faster rendering and enhanced performance of React apps. To begin with, the React Virtual DOM (Document Object Model) could be known as a tree data structure of plain JavaScript objects. Accordingly, React’s advantage over other frameworks is that it creates Virtual DOM as a replica of the true DOM, and whether the state change in a React component happens, it re-renders the Virtual DOM first, contrasts the older version to the new one, and only the essential minimum is altered from the real DOM instead of re-rendering the entire UI.

When you create React apps, this solution proves brilliant and straightforward in precisely the exact same moment. The React’s Virtual DOM acts as a layer between how things are supposed to look and the actual processes happening to render all of those things on the page.

4. ) React helps to construct easily testable rich user interfaces.

Front-end development with React contributes not to only performant but also highly testable applications. React itself makes it much easier to make a clean structure that is beneficial to analyzing, and this is why:

    • if you’re working with React, you don’t need to do any extra configuration of UI tests. As an alternative, you might use Jest, Facebook’s JS test taker that is configured right out of the box and works seamlessly with React.js applications.
    • If you opt to think of a new app using Create React App, Jest will proceed with it by default, so you will be able to execute tests fast.
    • Jest is a Node-based runner. Thus, when assessing a React JS app, a developer can run unit tests in a Node environment, not in an actual browser, by mocking components under evaluation.
    • Traditional UI test execution will be slow, but with React, UI tests are run very fast.
    • UI tests often wind up becoming brittle. But by individually testing single React components in a Node environment , you can stop flakiness and be certain test results’ reliability. That’s because, this way, you’re going to be in a position to test pure functions, which, unlike with traditional end-to-end UI tests, isn’t quite as time-consuming, both in terms of writing and maintenance.
    • if you are running unit tests using React, you can make certain it is not going to be a massive challenge to write these tests quickly and update them easily.






5. ) The React library helps developers boost their productivity.

It would be no exaggeration to say that everybody would rather get a tool or two good at improving their productivity and efficiency at work. React.js is a library that could boost programmer’s functionality and is recognized to be quite similar with Angular in this regard. What does React do exactly to help one achieve this?

In brief, developers’ productivity increases due to these React-provided possibilities:

JavaScript, TypeScript, and JSX.  Time is a valuable resource when it comes to software development. Using React in a project, developers can save time, deliver a product faster, and help a business begin generating profit without delay.

This advantage is rooted in React’s capability to work with JavaScript, TypeScript, and JSX. Writing on JavaScript, TypeScript, or JSX, one not only will find more security and fewer bugs but may also have the ability to create reusable components. This approach, allowing for code reuse, really boosts entire developer productivity.

DevTools.  In addition to the component reusability feature, React provides a set of useful React Developer Tools to enhance one’s productivity. These DevTools have the sort of a browser extension that might be set up on Chrome, Edge, and Firefox browsers.

They allow inspecting React component trees, monitoring and checking element state at any given time, and much more. They also can improve the developer experience by providing them with useful built-in Tracking tools. Thus, as opposed to writing console logs, manually adding dev print statements, or using specialized debugging tools, somebody may open React DevTools and see if everything about a part is accurate.

6. ReactJS can be SEO-friendly.

If you still hesitate whether React JS is the best, we have got another benefit to share! You may use React to create apps optimized for search engines.

When we speak about websites and internet apps (be it an SPA or a typical multi-page app), we should not neglect the value of consumer engagement. Among the best ways to increase it is to ensure that your web app or website is crawlable by search engines. Under specific circumstances, React can be equivalent to this job. How React, typically, uses JavaScript to load webpages is an important plus. But this can get tricky since the app’s internal information and markup are often loaded dynamically — it’s called client-side rendering — and therefore not entirely SEO-favorable.

This meansthe solution for this matter, basically, comes down to whether the app uses server-side or client-side rendering. Therefore, it’s easier for Google or other search engines to crawl a web app that uses server-side rendering to supply an HTML response when an individual or crawler strikes a page URL. This way, HTML is created on the server and the markup is sent back on the initial petition.

It takes effort and want the wisdom of these technologies as Gatsby.js or Next.js to prepare server-side rendering when generating React.js apps. However, the moment you ensure appropriate indexing of your app’s pages by search engines, your product will find a huge competitive advantage, and this outcome is totally worth it.

7. React developers get strong community support.

Being an open-source library, ReactJS has what it takes to keep bringing an increasing number of new-comers to its community, which makes it just stronger over time.

The feeling of belonging to a community is a fantastic foundation a software programmer can depend on when researching new technologies or working on a complex project. React developers will certainly get this feeling. The React library has become the expansion loop and appears to intend to remain there as long as possible.

As of this moment, React.js is the number five top-rated repository on GitHub with over 160k stars and over 5 million applications publicly admitting to using it. React includes a rich ecosystem to benefit from or contribute to. Regardless, finding one’s way around all this information will not be a substantial challenge as the React documentation is easily found on the official website.

The community is active, so you can get fast feedback or response to your question when you are feeling stuck. Presently, on StackOverflow, you’ll discover over 160k questions tagged react.js who have at least one approved answer. That is incredible how responsive the area is! So, after you encounter a problem, odds are someone has already had precisely the same problem, and there is a solution to it you will simply have to copy-paste it at the corresponding conversation thread.

Last but not least, another React’s distinctive feature is that, unlike a lot of other frameworks and libraries, it is a fulltime development team working day-by-day to make this technology better. Traditionally, open-ended jobs get together without fulltime developers and are being improved through the work of independent subscribers who are dedicated to the job to a particular level. React contributors’ loyalty is significantly deeper than that, which has a direct positive impact on React developers’ programming experience.


Front-end web development with React has been a popular trend in 2020 and will remain just as popular in 2021. The evidence for this statement is rock-solid.

Since its launching, the React library has always been evolving and advancing. At precisely the exact same moment, component-based architecture, React’s leaning towards functional programming theories, and other distinct features of this JS library that we’ve discussed above keep attracting a growing number of developers to the inviting and welcoming React community.
