# lists.do

> Process arrays and collections at the edge with functional utilities. Type-safe operations with automatic caching and sub-millisecond execution.

List Operations at the Edge, Zero Dependencies. Functional utilities for arrays and collections with automatic type inference and lazy evaluation. Filter, map, reduce, sort, and transform data at the edge.

lists.do is one of the primitives of Platform.do, in the Data layer (records, vocabulary and search). Every .do shares one grammar, Business-as-Code, and one SDK.
