How do I use Webpack for bundling my JavaScript files?

To use Webpack for bundling, first install it via npm with npm install --save-dev webpack webpack-cli. Then, create a webpack.config.js file to configure your entry and output settings.

What should I include in the webpack.config.js file?

In your webpack.config.js, you should define the entry point (your main JavaScript file) and the output path where the bundled file will be saved. For example:

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: __dirname + '/dist'
  }
};

How do I run Webpack after setting it up?

You can run Webpack by adding a script in your package.json like this:

"scripts": {
  "build": "webpack"
}

Then, execute npm run build in your terminal to create the bundle.

Can I use Webpack with other tools like Babel?

Yes, you can use Webpack with Babel! You just need to install Babel and its loader, then configure it in your Webpack config to transpile your JavaScript files.
