cartesianProduct
Generates the cartesian product of two iterables.
An array of tuples containing all possible pairs from the two iterables
Example
import { cartesianProduct } from "@temelj/iterator";
const colors = ["red", "blue"];
const sizes = ["S", "M", "L"];
const products = cartesianProduct(colors, sizes);
console.log(products);
// [
// ["red", "S"],
// ["red", "M"],
// ["red", "L"],
// ["blue", "S"],
// ["blue", "M"],
// ["blue", "L"]
// ]
permutations
Generates all permutations of the input iterable.
An array of arrays, where each inner array is a unique permutation
Example
import { permutations } from "@temelj/iterator";
const items = [1, 2, 3];
const perms = permutations(items);
console.log(perms);
// [
// [1, 2, 3],
// [1, 3, 2],
// [2, 1, 3],
// [2, 3, 1],
// [3, 1, 2],
// [3, 2, 1]
// ]
combinations
Generates all combinations of a specific size from the input iterable.
The iterable to generate combinations from
The size of each combination
An array of arrays, where each inner array is a unique combination of size n
Throws an error if n is negative
Example
import { combinations } from "@temelj/iterator";
const items = [1, 2, 3, 4];
const combs = combinations(items, 2);
console.log(combs);
// [
// [1, 2],
// [1, 3],
// [1, 4],
// [2, 3],
// [2, 4],
// [3, 4]
// ]
// Empty result when n is larger than the array
console.log(combinations([1, 2], 3)); // []
// Single empty array when n is 0
console.log(combinations([1, 2, 3], 0)); // [[]]
