Best practices in using F# collections

The F# types are mostly describing types that are not collection types. F# has its own unique collection types as well.

The F# collection features are mostly implemented as modules, with the namespace of Microsoft.FSharp.Collections. The following are the F# collection modules:

• Module Array: Basic operations on arrays

• Module Array2D: Basic operations on two-dimensional arrays

• Module Array3D: Basic operations on rank 3 arrays

• Module Array4D: Basic operations on rank 4 arrays

• Module ComparisonIdentity: Common notions of comparison identity used with sorted data structures

• Module HashIdentity: Common notions of value identity used with hash tables

• Module List: Basic operations on lists

• Module Map: Functional programming operators related to the Map type

• Module Seq: Basic operations on enumerable collections

• Module Set: Functional programming operators related to the Set type

List, Map, and Set are unique to F#.
