RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including @extra-array/cartesian-product. Try it out:
const array = require("extra-array");
var x = [1, 2, 3];
var y = [10, 20, 30];
array.cartesianProduct([x, y]);
array.cartesianProduct([x, y], ([a, b]) => a + b);
