Features of React JS And Why We Use React JS

Introduction:

React JS is a popular JavaScript library for creating mobile and online applications. Facebook produced React, which is a collection of reusable JavaScript code snippets for user interface (UI) creation.

ReactJS isn’t a JavaScript framework, so keep that in mind. Because it’s exclusively in charge of drawing the components of an application’s view layer, this is the case. To implement sophisticated functions, most front-end JavaScript developers use frameworks like Angular and Vue.

This post will go through the features of React, and why we use React JS in detail. If you want to learn more about React JS then join React JS Training in Chennai with Certification and Placement support for your career enhancement.

Features of React JS:

React has a few key characteristics that set it apart from other JavaScript libraries. These characteristics will be introduced in the following sections, along with an explanation of how they contribute to mobile and online application development.

JSX:

React components are created using JSX, a syntactic extension for JavaScript. Programmers use it to insert HTML code in JavaScript objects. Because JSX allows legitimate JavaScript expressions and function embedding, it may make even the most complicated code structures easier to understand.

JSX is a JavaScript syntactic extension that is used to create React elements. It’s used by programmers to embed HTML code in JavaScript objects. Because JSX allows legitimate JavaScript expressions and function embedding, it may make even the most complicated code structures easier to understand.

A web page is presented in a data tree form by the Document Object Model (DOM). Virtual DOM trees are stored in memory by ReactJS. React may update select areas of the data tree in this way, which is quicker than re-rendering the full DOM tree.

Virtual DOM:

A web page is displayed in a data tree structure using the Document Object Model (DOM). Virtual DOM trees are saved in memory by ReactJS. React may then apply modifications to particular areas of the data tree instead of re-rendering the full DOM tree, which is quicker.

ReactJS will construct a new Virtual DOM tree whenever data changes and compare it to the previous one to determine the fastest method to apply changes in the actual DOM. Diffing is the name for this method.

Rendering the modified version takes less time and requires fewer resources since UI alteration only affects selected areas of the real DOM tree. Large projects with a lot of user contact gain a lot from this strategy. Join React JS Course in Chennai with certification and placement support for your career enhancement.

Why We Use React JS:

Easy to Use:

Because it depends on simple JavaScript and a component-based approach, developers with JavaScript understanding may quickly learn how to utilize React. After just a few days of studying React, you’ll be able to start designing web-based applications.

Even if you aren’t familiar with JavaScript, there are several websites that provide free coding tutorials. Once you’ve mastered the fundamentals of JavaScript, go on to ReactJS to speed up the front-end development process.

Supports Reusable Java Components:

React allows you to reuse components that have already been created for other apps. Because ReactJS is open source, you may pre-build components, reducing the time it takes to design complicated web apps.

Furthermore, React allows you to layer components inside of other components to construct sophisticated functionality without bloating the code. It’s simple to manage each component because it has its own set of controls.

Easier Component Writing:

It’s easier to design React components now that JSX is included — users may construct JavaScript objects with HTML typography and tags. JSX also simplifies the rendering of numerous functions, keeping the code short without decreasing the app’s functionality.

Although JSX is not the most common syntactic extension, it has been shown to be useful in the construction of specific components and dynamic applications.

Create React App, React’s official command-line interface tool (CLI), simplifies single-page application creation even further. It comes with a contemporary build setup process and pre-configured tools, and it’s a great way to learn ReactJS.

High Performance:

Virtual DOM, as previously mentioned, allows ReactJS to update the DOM tree in the most efficient manner possible. React minimizes unnecessary re-rendering that might degrade speed by keeping Virtual DOM in memory.

Furthermore, React’s one-way data binding between elements simplifies debugging. Any changes made to the child components will have no effect on the parent structure, lowering the likelihood of mistakes.
