If you are new to webpack, you may want to start by reading this page or the Getting started section on the left.
webpack has a rich plugin interface. Most of the features are internal plugins using this interface. This makes webpack very flexible.
webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredible fast on incremental compilation.
webpack allows to split your codebase into chunks. Chunks are loaded on demand. This reduces initial loading time.
