What is ReactJS?

React is a front-end JavaScript toolkit that is used to create UI-component based user interfaces. It is free, open-source, declarative, adaptable, and efficient. Jordan Walke built ReactJS for large and complex web interfaces and single-page applications at Facebook. According to a Statista poll, 40.14 per cent of respondents prefer to utilize ReactJS in their projects. ReactJS has pushed front-end programming to new heights since its inception. ReactJS is used on over 2,000,000 websites, according to Facebook. PayPal, and a slew of other well-known websites use React.

React is a JavaScript toolkit for building amazing web applications that were created and supported by Facebook in 2011. Initially, it was only for internal use. React powered Facebook's and Instagram's news feeds in 2011 and 2012, but it wasn't until 2013 that it was made available to the general public.

Since then, React has earned widespread acclaim from its users as well as financial backing from its creator, Facebook. ReactJS is now on its 17th version, which means it is updated twice a year on average. Such upkeep results in a solid product, which is an agile, stable, adaptable, modern library with a vast variety of developer tools.

You may be asking why you should utilize ReactJS now that you know what it is. So, let's have a look at some of the most compelling reasons to use ReactJS for your forthcoming project's front end.

i) Simple to Understand

We're not claiming that you'll be able to master ReactJS in a week; it could take months or even a year. However, unlike Angular, you won't need to learn any other languages to get started, such as typescript and ECMAScript 6 (ES6). All you need to get started with ReactJS is a basic understanding of HTML, CSS, and, most crucially, JavaScript; the rest will come naturally.

ii) Data Flow in One Direction

Unidirectional data flow, often known as one-way data flow, refers to data that has just one path to other sections of the application. It signifies that the data from the parent component cannot be updated by the child component. Props are data from the parent component in React, which guarantees that developers follow a clean data flow and that you have better control over data. 

iii) Components that can be reused

Component-based architecture is used in React. Components are a minor feature that is part of the user interface. It can be anything from a chat window to a comment feed to a dropdown menu. Each of these UI components lives in the same space but interacts with each other independently. React allows you to create reusable, self-contained components. However, in order for a component to be reusable, it must accept data via props and deliver the result via a function given by props. The render prop is a function that tells the component what content it needs to render and allows you to reuse functionality throughout the component.

iv) Developer Resources

Another reason why developers prefer ReactJS is the availability of React Developers Tools. The React developers tools are a collection of frameworks, extensions, and modules designed to make React programming easier. As a front-end developer, you may leverage code generators, testing utilities, debugging extensions, and other ReactJS tools to create more stable code and applications while cutting down on development time. Several React developer tools are available as extensions for popular web browsers like Firefox and Chrome.

v) Virtual Document Object Model

Another feature that makes React more developer-friendly is the virtual DOM. VDOM is a programming concept that keeps an ideal model of a user interface in memory and then synchronizes it with the real DOM, a process known as reconciliation. This method makes use of the declarative React API, which allows you to tell React what state your UI should be in. The DOM is then checked to see if it fits this state. To various people, "virtual DOM" can signify different things. The term is frequently used in React to refer to the objects that represent the user interface. Fibres are used by React to store information about the component tree. This section summarizes the event handling, manual DOM updating, and attribute manipulation that you would otherwise use to construct the app.

vi) Native React

When you use ReactJS for UI development, you get a freebie: React Native. React Native combines the greatest aspects of both native and React programming. You can construct a version of a platform-specific component that allows code to be shared across platforms from a single codebase. React Native allows a single team to manage two platforms using a single technology: React. As a result, it's easier for developers to migrate to React Native and build native mobile apps without sacrificing user experience.

vii) Flux

Another reason why developers prefer ReactJS is Flux. Facebook's Flux application architecture is used to create client-side web apps using React. Flux is a view that works with React and follows the Unidirectional Data Flow concept. When an application has dynamic data that needs to be updated quickly to reduce run-time errors, Flux can be employed. Flux was created with the goal of generating operations that are orchestrated by a central dispatcher in order to keep stores updated.

viii) Redux

Redux seems to be a state container for JS apps that is predictable. Redux and React can be used together. Redux makes it easier for developers to create web apps that work in a variety of environments, behave consistently, and are simple to test. React is a wonderful alternative for front end developers since Redux provides live code editing and a debugger to make the development process easier.

ix) A large support system

Because Facebook created React, it is still maintained by Facebook and independent contributors all across the world. React's GitHub Repository has over 165k starts and is one of GitHub's most popular repositories. React flux is a React Developers community with over 110k members that helps solve and share React-related difficulties.

x) JavaScript XML (JSX)

Facebook created JavaScript XML, a syntax extension for JavaScript. The goal of JSX is to bring the functionality of HTML structures into JavaScript. There is no need to separate HTML and JS scripts if a developer uses JSX. With ReactJS, you may use declarative HTML syntax in JavaScript code. Developers may quickly construct tidy and manageable code by passing ReactJS and HTML elements into the browser's tree structure. Furthermore, using JSX with Virtual DOM increases the efficiency and performance of ReactJS apps.

Legacy Code Migration Made Simple Legacy code may appear to be a curse for a development team. ReactJS, on the other hand, is a technology that can not only be useful but also replace something old and inefficient. Some firms require this capability because migration is, without a doubt, a better alternative than developing the same application from the start. You won't need to do that if you're migrating from an older system to a new one using React. You may just add the React code into your old web project for this reason, and it will run without any issues.

Overall, in 2022, React is a useful and up-to-date tool for web app development. Because it gives developers development speed, performance, and ease of maintenance, this library is capable of building true web masterpieces. You can use ReactJS to create complicated user interfaces, Progressive Web Applications (PWAs), and, in general, anything (including large-scale projects) that requires frequent page updates.
