What are JSX 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.
Why is JSX faster? ›
JSX performs optimization while compiling the source code to JavaScript. The generated code runs faster than an equivalent code written directly in JavaScript.
Is JSX only for React? ›
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) .
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.
What are the benefits of new JSX transform? ›
The main benefits of the new JSX transform are:
- It enables you to use JSX without having to import React.
- The compiled output relatively improves the bundle size.
- It lights a path for future improvements where you'll have only a few concepts to learn React.
Is it necessary to use JSX in React? ›

What are the different types of JSX? ›
Built-in Object Types
- Object. Object class is the root class for all objects.
- Array. <T> ...
- Map. <T> ...
- Boolean, Number, String. Internal types used for applying methods against primitives. ...
- JSX. The class provides some methods for controlling the runtime environment.
What is the purpose of React State? ›
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.
