combinatorial v1.0.3

combinatorial

Given n arrays, iterate over all possible combinations of values by taking a single value from each array.

Example

const combinatorial = require("combinatorial");

const a = [1, 2, 3];
const b = ['a', 'b', 'c'];
const c = ['A', 'B', 'C'];
const result = [];

combinatorial(a, b, c, (a, b, c) => {
	result.push([a, b, c]);
});

// result will be the following:
[
	[1, 'a', 'A'], [1, 'a', 'B'], [1, 'a', 'C'],
	[1, 'b', 'A'], [1, 'b', 'B'], [1, 'b', 'C'],
	[1, 'c', 'A'], [1, 'c', 'B'], [1, 'c', 'C'],
	[2, 'a', 'A'], [2, 'a', 'B'], [2, 'a', 'C'],
	[2, 'b', 'A'], [2, 'b', 'B'], [2, 'b', 'C'],
	[2, 'c', 'A'], [2, 'c', 'B'], [2, 'c', 'C'],
	[3, 'a', 'A'], [3, 'a', 'B'], [3, 'a', 'C'],
	[3, 'b', 'A'], [3, 'b', 'B'], [3, 'b', 'C'],
	[3, 'c', 'A'], [3, 'c', 'B'], [3, 'c', 'C']
