Tell us what’s happening:
I don’t know how can I solve this problem?
"The sum function uses the … spread operator on the args parameter.
"
Your code so far
const sum = (function() {
"use strict";
return function sum(...n) {
return n.reduce((a, b) => a + b, 0);
};
})();
console.log(sum(1, 2, 3)); // 6
