React JSX Explained

React JSX is a syntax extension for JavaScript that allows you to write HTML-like code in your React components. JSX makes it easier to write and understand your code by providing a familiar HTML-like structure.

Here’s an example of JSX code in a React component:

        
            const element = 
Hello, World!
;
        
    

In the above code, the {} brackets are used to embed JavaScript expressions within JSX. This allows you to mix JavaScript logic and HTML markup in your components.

When you write JSX code, it is transpiled into regular JavaScript code by tools like Babel before being rendered by the browser. This is because browsers do not natively understand JSX syntax.

React components can be created using JSX syntax as shown in the following example:

        
            class App extends React.Component {
                render() {
                    return (
                        

                            
Hello, React!
                            
This is a React component written in JSX.
                        
                    );
                }
            }
        
    

When you write JSX code in your React components, you can also use custom components and props to build reusable and modular UI components.

In conclusion, JSX is a powerful and easy-to-use syntax extension for JavaScript that makes writing React components more intuitive and efficient. It allows you to combine HTML-like markup with JavaScript logic, resulting in a more declarative and readable codebase.
