What is JSX and its advantages? ›

What is JSX? JSX stands for JavaScript XML. JSX allows us to write HTML in React. JSX makes it easier to write and add HTML in React.

Key Features of JSX

It allows you to insert large blocks of HTML code within parentheses. JSX makes the process of developing React applications simpler. Once the code is completed, a JSX expression can be transformed into a regular JavaScript function call.

JSX is a syntax extension for JavaScript that lets you write HTML-like markup inside a JavaScript file. Although there are other ways to write components, most React developers prefer the conciseness of JSX, and most codebases use it.

Here are the key differences: Syntax: JSX is a syntax extension for JavaScript that allows you to write HTML-like code within JavaScript. It introduces XML-like tags and attributes to create React elements. JS, on the other hand, is plain JavaScript code without any special syntax or extensions.

Unlike HTML, JSX enables the embedding of JavaScript expressions and facilitates the creation of reusable components, promoting a more dynamic and efficient approach to web development.

Due to syntax differences JSX uses elements that look like HTML tags, but they are actually JavaScript expressions that create React components. Browsers don't have the built-in mechanisms to parse and render these custom elements.

It is a JavaScript extension where we can embed valid JavaScript objects into HTML elements. JSX makes Code easier to read and understand. Usually, HTML and JavaScript are written separately but React creates component.

JSX performs optimization while compiling the source code to JavaScript. The generated code runs faster than an equivalent code written directly in JavaScript.

JSX is not a requirement for using React. Using React without JSX is especially convenient when you don't want to set up compilation in your build environment. Each JSX element is just syntactic sugar for calling React. createElement(component, props, ...children) .

Why is it called JSX? ›

JSX stands for “JavaScript XML,” and it is a syntax extension to JavaScript based in ES6, the newest “version” of JavaScript. JSX allows you to write HTML in React by converting HTML into React components, helping you to more easily create user interfaces for your web applications.

JSX is not a requirement for using React. Using React without JSX is especially convenient when you don't want to set up compilation in your build environment. Each JSX element is just syntactic sugar for calling React.

The state is a built-in React object that is used to contain data or information about the component. A component's state can change over time; whenever it changes, the component re-renders.
