An inverted index that allows javascript objects to be easily serialised and retrieved using promises and map-reduce

Utilities for consuming, creating and manipulating node streams.

Async enabled each(), map(), filter() functions that work just like their standard counterparts, but can be used with async/await and also provide concurrency limiting. Includes built-in typings and JSDoc comments for IntelliSense documentation.
