Webpack

Overview

Webpack bundles JavaScript. It can also bundle other assets such as css, and images. I can compile SASS.

It can serve as an alternative to Gulp.

Pros

You put includes into the source and set an entry point for Webpack. This avoids having to update any Webpack configuration to accommodate changes in the source code. Easier to maintain. <ref.Webpack or Browserify & Gulp: Which Is Better? - toptal.com</ref>
