Question

AI Bootstrap Builder · Accepted 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.


        
        // 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']
                    }
                ]
            }
        };

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. ✅ Answered with JavaScript best practices.
