REACT JS

React?is a?JavaScript library?for building?user interfaces?(UIs) on the web. React is a declarative, component based library that allows developers to build reusable UI components and It follows the Virtual DOM (Document Object Model) approach, which optimizes rendering performance by minimizing DOM updates. React is fast?and works well with other tools and libraries.

Features of React

Component-Based Architecture :

React provides the feature to break down the UI into smaller, self-contained components. Each component can have its own state and props.

JSX (JavaScript Syntax Extension) :

JSX is a syntax extension for JavaScript that allows developers to write HTML-like code within their JavaScript files. It makes React components more readable and expressive.

Virtual DOM :

React maintains a lightweight representation of the actual DOM in memory. When changes occur, React efficiently updates only the necessary parts of the DOM.

One-way Data Binding :

One-way data binding, the name itself says that it is a one-direction flow. The data in react flows only in one direction i.e. the data is transferred from top to bottom i.e. from parent components to child components.

Performance :

React uses virtual DOM and updates only the modified parts. So , this makes the DOM to run faster. DOM executes in memory so we can create separate components which makes the DOM run faster.

Components :

React divides the web page into multiple components as it is component-based. Each component is a part of the UI design which has its own logic and design.

Single-Page Applications (SPAs) :

React is recommended in creating SPAs, allowing smooth content updates without page reloads. Its focus on reusable components makes it ideal for real-time applications.

React. js, a frontend-focused JS library used mainly for building single-page and multi-page interfaces, is one of the most popular programming technologies worldwide, and the number of companies reaching out to it proves its solid position.
