permutations

function

function permutations<T>(inputArray: Iterable<T>): T[][]

Builds all possible orders of all elements in the given array. Ignores equality of elements, meaning this will always return the same number of permutations for a given length of input.

inputArray: Iterable<T>

The array to build permutations from.

Returns

An array of all possible permutations of the given array.
