An array is a collection of values, stored contiguously.

A functional query engine, that operates over streams of js objects, and can be optimized via database indexes.

map-filter-reduce queries for flumedb

A scuttlebot plugin for querying data. With [map-filter-reduce](https://github.com/dominictarr/map-filter-reduce) you can write pretty flexible queries, similar to SQL, but more javascripty.
