What are the best practices for configuring Webpack and Babel?

When configuring Webpack and Babel, it's essential to keep your configuration modular and maintainable. Start by using a separate configuration file for each environment (development, production). Also, consider using Babel presets like @babel/preset-env to ensure compatibility with the latest JavaScript features.

Should I use Babel for all my JavaScript files?

It's generally a good idea to use Babel for files that need to support older browsers or environments. However, if you're using modern JavaScript features and targeting only modern browsers, you might not need Babel for every file.

How can I optimize my Webpack build for production?

To optimize your Webpack build for production, enable minification, use the 'mode' option set to 'production', and consider using plugins like TerserPlugin for JavaScript minification and MiniCssExtractPlugin for CSS.

What are some common mistakes to avoid in Webpack and Babel configuration?

Common mistakes include not specifying the correct entry and output paths, failing to include necessary loaders for file types, and neglecting to set up source maps for easier debugging.
