If you're engaged in a front-end web application, React JS is almost certainly a programming tool that has been recommended to you. Is it, however, the best alternative for your project? “Yes” has been the response for numerous companies. As of the most recent statistics from  SimilarTech, React JS has been utilized on over one million websites and 298,000 distinct domains to date. Sounds impressive, doesn’t it?

What is React JS

This is a free, open-source JavaScript library for developing user interfaces. The library was originally created by an engineer working for Facebook, Jordan Walk, in 2011. For this reason, React JS is supported by the company's large community and a wide pool of web developers. The React JS team published a helpful article describing the vision behind the framework and how you may build your applications more effectively by working with different team members. React JS is a declarative library where a developer need not tell all the tiny details, but just enough to say since the framework can fend for its own sake. In other words, you don't need to operate the DOM as you do for example with jQuery. Moreover, the framework divides the page into components, some of which can be a child of other components. For example, the search bar on the page can be considered as a separate component. What is more, with Node JS, React JS may be used as a server language, and with ReactNative, it can be used for mobile apps. Based on Stack Overflow research and also Statista, React JS has been the most beloved web framework for developers around the world for several years. In addition, it is being used today by more than 7.4 million live websites.

How React JS Works - Let`s Take a Closer Look

React JS is notable for its simplicity and velocity of use due to the availability of shortcuts and reusable UI elements. Any of your front-end mobile and web apps may use React JS to handle the view layer. The virtual DOM model, operating as a "DOM tree" helps to define a logical structure for all the docs in the library. The virtual DOM works fast enough because nothing gets drawn on the screen and there is simply no need for reflow or repaint. React JS was originally designed to run in the browser, but with the introduction of Node JS, it is possible to use its trees on the server-side.

Projects that Use React JS

Analysis by SimilarTech clearly indicates that React JS is widely popular around the world, especially in the US and China. This analysis demonstrates how many websites in each country are built with React JS. 

Take a look at some amazing React implementations. React JS has been selected by thousands of enterprises, including some Fortune 500 firms, for their websites and mobile apps. Tesla, Tencent QQ, Airbnb, Walmart are just a few of the well-known companies that have used the React Native framework to create mobile apps. The React web framework, on the other hand, is presently used by well-known firms such as Netflix, Paypal, NASA, BBC, Lyft, and the New York Times, to mention a few. The argument is that React & React Native is used by so many successful and Fortune 500 firms, thus it must be a really effective frontend and mobile app development platform.

Main Advantages of React JS

React JS has a number of advantages. Let's look at the main benefits of React JS to discover why it's different from other front-end development frameworks.

advantages of react.js
  • Easy to Learn & Easy to Use

One of the key advantages of React JS is that most programmers who have a good knowledge of JavaScript are capable of mastering React in a matter of days. React is considerably easier to grasp than interface frameworks such as Angular and Vue. It's one of the primary reasons React has achieved so much popularity in such a short period of time. It aids firms in swiftly completing tasks. Its extensive use also implies that in the labour market you can always find higher qualified candidates depending on your own requirements. You'll have a far higher chance of quickly implementing this new capability into your existing IT maintenance structures if you can simply move the completed application from your development team to your IT maintenance staff. 

  •  Stable Code Structure

React JS uses downward data flow to ensure that any changes to its child structure do not affect the parent structure. As a result, anytime a developer makes changes to an object, all he or she has to do is adjust its state and make the necessary modifications. Just one single element will be changed in this manner. As a consequence of this data flow and structure, the application's code is more stable and runs more smoothly.

  •  Simplified Scripting

JSX, a free syntactic extension for React JS, is included to enable writing your own components. Such components essentially allow HTML quoting thus making all subcomponent rendering a pleasure for developers. JSX has already been used for developing custom components, constructing high-volume apps, and transforming HTML mockups into  React JS element trees, despite the fact that there have been numerous disagreements on the subject.

  •  Faster Rendering

Because of React's tree concept, a bug at the top can propagate throughout the tree. To address this issue, the development team of Facebook designed a virtual document object model (DOM) that better distributes traffic and requests. When weighing the benefits and drawbacks of React JS, it's evident that it's a game-changer for the library. For high-traffic applications, it delivers critical speed and precision. Another reason why some of the world's top websites use React for their bespoke applications is because of this.

  •  Creating Dynamic Web Applications Becomes Easier

A blank HTML page is the starting point for React JS web applications. In JavaScript, it builds the starting state dynamically. Plain javascript programs, on the other hand, begin with a server-side-created UI. Because of its modular nature, React code is easier to maintain and more versatile than other frontend frameworks. Businesses save a significant amount of time and money as a result of this flexibility.

  •    Provides Amazing Developer Tools

Acquiring new technology and applying them to real-world tasks can be both entertaining and helpful, but only if done right. Facebook recognizes the above, which is why their React JS framework now includes much-needed React development tools and Chrome development tools. Such React JS tools primarily aid developers in locating child and parent components, observing component hierarchies, and inspecting the current state and properties of components.

  •   UI-focused Designs

React may be dubbed a "learn once, write anywhere" framework since it follows the same design principles in both online and mobile app development, making the transition easier. You can create a rich UI for native apps using simple JavaScript and React, which are compatible with both iOS and Android platforms. React Native developers note the portability and ability to reuse components, real-time reload and modular design, open-source, and rich ecosystem as some of the benefits of React JS in mobile app development. We may name mobile applications like Skype, Tesla, Airbnb, and Walmart as examples of React Native in action. Not to mention Instagram and Facebook, which are true innovators and early adopters.

  •      SEO-friendly

Search engine optimization is the key to every online business's success.

As per Moz, the faster an app's page load time and rendering performance are, the better it will rank on Google. React, as compared to other frameworks, considerably reduces website load time, which notably aids organizations in obtaining the top spot on Google's Search Engine Result Page.

Ok, but What About the Pitfalls?

  • Pace of Development

React is a dynamic and ever-changing library. Updates are released every few months, and fresh programming knowledge emerges on a near-daily basis from react's massive community. For some programmers, this might be tough to keep up with.

React, on the other hand, has been around long enough as a technology to be considered a mature library. Because the foundation of this product has stabilized, there are significantly fewer adjustments. The majority of the upgrades are minor and non-essential. This problem is more of a tie when it comes to weighing the benefits and drawbacks of React JS.

  •  Poor Documentation

Since the whole React environment is growing so quickly and new technologies are being released so often, documentation is often not keeping up. Depending on how you look at it, this might be a benefit or a downside of React JS. This is a serious negative that must be weighed against the advantages of React JS. However, many people find that using alternative solutions like Redux and GraphQL can help them get over these issues.

  • SEO Can Still be Tricky

React JS recently demonstrated that it can frequently overcome Google's difficulty interpreting JavaScript. However, it is not without flaws. That means your SEO professionals will have to pay extra attention to your single-page applications, which must be extensively tested and verified against Google's search algorithms. To be honest, every SPA has this SEO problem. In fact, SEO professionals advise putting your apps via the Google Search Console tools so you can observe how well they interact with the search engine firsthand. Finally, programmers may tackle the problem with technologies like Next JS or Gatsby JS.

In What Cases React JS Will Be the Best Solution?

React JS stands as a responsive, streamlined, and simple-to-use JS framework that is suitable for both large and small businesses. It's easy to use and scales well for companies with a lot of user-facing features in a high-traffic environment. It's an excellent library to utilize if you have a website that has to execute many functions at the same time, and the fundamental simplicity of the language makes future updates simple. If you believe you'll be sticking with React JS for a long time, this library is an excellent bet.

When You Should Avoid Using React JS

React JS offers a lot of advantages and is versatile enough to be effective for most businesses. However, it is not always the best option. Vue JS, for example, can be a good choice if you require a library that allows you to simply add new features. If you're not confident about your app's future, you might want to consider other options. Migrating React into other libraries may be challenging and time-consuming. And dealing with this situation, later on, might be quite costly. Use Vue JS or Angular JS instead of TypeScript or other predefined templates if you suspect you'll be transferring to TypeScript or other premade templates.

Wrapping Up

There are several persuasive advantages to utilizing React JS without even hesitation. It is one of the most popular JS libraries because of its virtual browser DOM, interactive UIs, JSX compatibility, and zippy component-based structure. It has actually delivered on its promise of allowing programmers to create large-scale systems with dates that vary over time. This makes it an excellent choice for businesses of all sizes, from startups to enterprises, in virtually any industry.
