JSX stands for JavaScript XML. It is a syntax extension for JavaScript that allows us to write HTML-like code within JavaScript. JSX is commonly used with React, a popular JavaScript library for building user interfaces.
In JSX, we can write HTML elements, attributes, and content directly within JavaScript code. It provides a concise and structured way to define the structure and appearance of UI components.
Here’s an example of JSX code:
const element = <h1>Hello, JSX!</h1>;
In the above code, we are using JSX to define a
element with the content “Hello, JSX!”. This JSX code can be used within JavaScript functions or assigned to variables.
To use JSX in a web page, we need to transpile it into regular JavaScript using a tool like Babel. Here’s how the above JSX code would look after transpiling:
const element = React.createElement("h1", null, "Hello, JSX!");
This transpiled code creates a React element using the React.createElement() function, which takes the element type, attributes (null in this case), and content as arguments.
Overall, JSX simplifies the process of creating and manipulating HTML elements within JavaScript, making it easier to build dynamic and interactive user interfaces.
