JSX Syntax and Benefits

Hello, students! In the previous topic, we learned about handling and displaying dynamic data in React.

In this class, we will learn about JSX.

JSX is an extension of JavaScript that allows writing HTML code within JavaScript.

JSX makes writing React components easier and more readable.

JSX Syntax

The syntax of JSX is similar to HTML syntax.

We can use HTML tags, attributes, and content within JSX.

For example, the following code is a JSX example:

<div>
  <h1>My component</h1>
  <p>Hello, world!</p>
</div>

This code renders a header and a paragraph in the user interface.

Benefits of JSX

JSX offers various benefits for React development, including:

• Ease of Writing: JSX makes writing React components easier and more readable.
• Readability: JSX makes React code more readable for HTML and CSS developers.
• Organization: JSX helps organize React code in a more logical format.

JSX Example

Let’s see an example of how to use JSX to render a list of products:

const products = [
  {
    name: "Product 1",
    price: 100,
  },
  {
    name: "Product 2",
    price: 200,
  },
];

const MyComponent = () => {
  return (
    <div>
      <ul>
        {products.map((product) => (
          <li key={product.id}>{product.name}</li>
        ))}
      </ul>
    </div>
  );
};

This code renders a list of products in the user interface.

The code uses JSX to render HTML tags <ul> and <li>.

The code also uses JSX to render the content of the <li> tags.
