What are Babel and Webpack, and how do they work together?

Babel is a JavaScript compiler that converts modern JavaScript into a version compatible with older browsers. Webpack is a module bundler that takes your JavaScript files and other assets, bundles them into a single file, and optimizes them for production.

Why do I need Babel if I'm using Webpack?

You need Babel to ensure that your modern JavaScript code can run in older browsers. Webpack handles the bundling, but Babel ensures compatibility.

Can you give me an example of how to set them up together?

Sure! First, install Babel and Webpack via npm. Then, create a webpack.config.js file to configure Webpack, and a .babelrc file to set up Babel presets. Finally, use Webpack to bundle your files, and Babel will transpile them during the process.

What are some common Babel presets I should use?

Common Babel presets include @babel/preset-env for modern JavaScript features and @babel/preset-react for React applications.
