Combinatorial Methods

These methods create sequences of the very large combinations of values.

cartesianProduct

Generates sequence of the Cartesian product of an arbitrary number of columns of data.

Usage

const sequence: Seq<[string, number]> = cartesianProduct(
  ["a", "b", "c"],
  [1, 2, 3],
)

Type Definition

type cartesianProduct = <T>(...inputs: T[][]) => Seq<T[]>

powerSet

Generates sequence of Sets of a Power set.

Usage

const sequence: Seq<Set<string>> = powerSet(["a", "b", "c"])

Type Definition

type powerSet = <T>(...items: T[]) => Seq<Set<T>>

combination

Generates sequence of Sets of a Combination of a given length.

Usage

const sequence: Seq<Set<string>> = combination(["a", "b", "c"], 2)

Type Definition

type combination = <T>(items: T[], size: number = items.length) => Seq<Set<T>>
