Answer

Webpack is a powerful module bundler for JavaScript applications. It is used to bundle JavaScript files for usage in a browser and can also transform, bundle, or package any resource or asset.

<!-- BEGIN COPY / PASTE -->
        // Webpack configuration example
        const path = require('path');

        module.exports = {
            entry: './src/index.js',
            output: {
                filename: 'bundle.js',
                path: path.resolve(__dirname, 'dist')
            },
            module: {
                rules: [
                    {
                        test: /\.css$/,
                        use: ['style-loader', 'css-loader']
                    }
                ]
            }
        };
        <!-- END COPY / PASTE -->

Additional Comment:

Webpack's "entry" property specifies the entry point of your application.
The "output" property defines the output file and location.
The "module" property allows you to define loaders, which transform files before they are added to the bundle.
Webpack can handle not only JavaScript but also CSS, images, and other assets.
It is commonly used in modern web development to optimize and manage dependencies efficiently.
