Part 1 function getTotal() { //convert object to an array var args = Array.prototype.slice.call(arguments); if (args.length === 2) { return args[0] + args[1]; } else if (args.length === 1) { return function(num2) { return args[0] + num2; }; } } console.log(getTotal(10, 20)); console.log(getTotal(5, 40)); console.log(getTotal(3)(30)); console.log(getTotal(8)(12)); Output: 30 45 33 20 Process finished
