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
Type Definition
const sequence: Seq<[string, number]> = cartesianProduct(
  ["a", "b", "c"],
  [1, 2, 3],
)
type cartesianProduct = <T>(...inputs: T[][]) => Seq<T[]>
powerSet
Generates sequence of Sets of a Power set.
Usage
Type Definition
const sequence: Seq<Set<string>> = powerSet(["a", "b", "c"])
type powerSet = <T>(...items: T[]) => Seq<Set<T>>
combination
Generates sequence of Sets of a Combination of a given length.
Usage
Type Definition
const sequence: Seq<Set<string>> = combination(["a", "b", "c"], 2)
type combination = <T>(items: T[], size: number = items.length) => Seq<Set<T>>
