React JSX Expressions

JSX Expressions

One of the strongest features of JSX is that it allows you to embed JavaScript expressions directly inside your HTML. To do this, you simply wrap your JavaScript code inside curly braces {}.

Using Expressions

You can evaluate variables, perform mathematical operations, or even call complex functions inside these curly braces.

const name = "John Doe";
const element = <h1>Hello, {name}!</h1>;

const mathElement = <p>5 + 5 is equal to {5 + 5}</p>;

JSX will execute the JavaScript expression inside the curly braces and return the result dynamically into your outputted markup.
