Why Should You Use React JS For Web App Development?

Choosing the simplest front-end technology nowadays may be a big deal for companies and developers. There are quite a few technologies within the market, and each designed to realize different requirements. React JS is one such technology that almost every company uses nowadays. With the rising popularity of React JS, there has been an enormous improvement within the domain of front-end web app development.

Before deep-diving into that, allow us to first have a look at what React JS is.

Facebook created React JS, an open-source JavaScript library for designing rich and fascinating web apps fast and efficiently with minimal coding. The primary objective of React JS is to produce the most effective possible rendering performance. Rather than being engaged on the whole web app, React JS allows a developer to break down the complex UI into simpler components.

In 2011, Facebook created React JS for its own use. In 2012, Instagram, a subsidiary of Facebook also started using it. And in 2013, Facebook made it open source and since then React JS has inevitably revolutionized the globe of web application development. Many Fortune 500 companies have implemented React JS for web-app development. You might know that over 1,200 developers and 90,000 sites use React JS. Top organizations like Facebook, Uber, PayPal, Instagram, and Airbnb use it to resolve user interface-related issues.

But why is React JS so popular among developers? Here are the best possible reasons:

Virtual DOM (Document Object Model)

Virtual Document Object Model is among the foremost popular features of React JS. It allows developers to implement some smart workarounds. Thereby, it ensures fast re-rendering of components, which is important since the information must be displayed immediately and effectively. 

Virtual DOM allows memory data to convert into components. The idea of Virtual DOM helps React JS to understand when exactly to re-render or when to ignore some specific pieces of DOM because it can detect when the information has changed.

Single page Web Application

With Virtual DOM React JS enabled developers to implement server-side rendering while not having to update the full view anytime during an update. This turned out to be an excellent feature to have while creating single-page applications. While building a dynamic front-end or a SPA, client-side routing is required to confirm a fast navigational experience for the end-user. Developers can still use React JS on the client-side and implement navigation. Eventually, the initial render uses server-side rendering, and also the subsequent navigations behave sort of like a SPA.

Usage of Components & Code Splitting

Components allow developers to interrupt complex UI. The concept of components is what makes React JS unique. In React, an application contains components. Ideally, developers start with building small components like buttons, checkboxes, dropdowns, menus, etc., and build wrapper components around these smaller components. Thus, rather than worrying about the whole web app, it makes it possible to break the complex UI/UX development into simpler components.

Performance

React JS yields better performance than other Javascript-based languages like Angular, VueJS. Because of Virtual DOM, splitting of code into multiple components, the performance of React JS is incredibly fast.

Code Simplicity

React JS is remarkably simple and versatile. It allows developers to jot down their apps within JavaScript. JSX is one of all the best features that not only make React JS easy but fun too. 

Developers can easily make a replacement UI feature and see it appear in real-time. It brings HTML directly into your JS. Rapid development and React’s small API combined to make an amazing developer experience thus making it very simple to understand and use.

Official Support and Community

React JS includes a massive active community and officially available resources. React is heavily employed in the Facebook app, website, and also Instagram. That’s why Facebook is deeply committed to making React JS strong and up to date. 

Do you want to know about the recognition amongst the developers?  If so, you can find almost 250k questions about React and related libraries. And its GitHub Repository has over 164k Stars, making it one of the five most repositories on GitHub.

Reliable testing

React’s design is extremely user-friendly for testing. Developers require little or no configuration for testing in React compared to Traditional UI browser testing. The standard UI browser testing is slow. But command-line testing is fast, and developers can run a substantial amount of test suites at a time.

With this gaining amount of recognition and advantages, many organizations and businesses use React JS for developing a good range of applications. React JS provides various tools to implement various use cases.

Here are a number of those use cases

  • Businesses can generate a static site with React using tools like Gatsby.
  • Dashboards or Data visualization tools are one amongst the foremost popular use-cases of React JS. With the assistance of Virtual DOM, Isomorphic javascript, reusable components, organizations can easily build user-friendly dashboards especially in projects where BI and Machine-learning are used for data visualization.
  • Social Networking systems are another popular use case of React JS where React JS as a UI library fits perfectly.
  • Ecommerce or retail businesses heavily use React JS for their websites. Thanks to the usage of component reusability, state management, eCommerce websites have improved performance, efficiency, and lower memory consumption.
