base: Core data structures and operations

[ bsd3, library, prelude ] [ Propose Tags ]

Haskell's base library provides, among other things, core types (e.g. Data.Bool and Data.Int), data structures (e.g. Data.List, Data.Tuple and Data.Maybe), the Control.Exception mechanism, and the System.IO & Control.Concurrent operations. The Prelude module, which is imported by default, exposes a curated set of types and functions from other modules.

Other data structures like Map, Set are available in the containers library. To work with textual data, use the text library.
