Key Features of Webpack

1. Module Bundling: Combines all your JavaScript modules into a single file (or multiple files) to optimize performance.
2. Code Splitting: Divides code into chunks for improved loading times.
3. Loaders: Transforms files into modules (e.g., converting TypeScript to JavaScript or processing CSS and images).
4. Plugins: Extend Webpack’s capabilities with tools like HtmlWebpackPlugin and MiniCssExtractPlugin.
5. Hot Module Replacement (HMR): Updates your code in the browser without a full page reload.
6. Tree Shaking: Removes unused code to minimize the bundle size.
