One may also ask, does webpack use Terser?
Webpack performs minification in production mode using Terser by default. Besides JavaScript, it’s possible to minify other assets, such as CSS and HTML too.

- Set the NODE_ENV to production . This tells some packages, like React, to not include debug code.
Subsequently, how does webpack improve performance?
How we improved webpack build performance by 95%
- enabling caching on the babel-loader improves performance by 26%
- enabling caching and parallel processing with uglifyjs-webpack-plugin v1 improves performance by 45%
- NOT exporting an array of configurations from webpack.config.js improves performance by 28%
