Tell us what’s happening:
my solution works but i want to understand how it works.
Your code so far
const sum = (function() {
"use strict";
return function sum(...args) {
//const args = [ x, y, z ];
return args.reduce((a, b) => a + b, 0);
};
})();
console.log(sum(1, 2, 3)); // 6
console.log(sum(0,1,2));
