The document discusses the concept of CommonJS, emphasizing the need for a standard library and consistent APIs across various JavaScript platforms. It outlines how CommonJS aims to facilitate code sharing and modularity among developers through a collaborative approach to building specifications and standards. Current statuses include the ratification of modules and packages, with ongoing efforts to expand and improve the ecosystem.

This will allow you to SWAP OUT PACKAGES depending on
the environment your application is running in WITHOUT
HAVING TO WORRY ABOUT CONFLICTS. EVER!
