Succinct version of the square function written in ES6

	const square = (...args) => args.map((arg) => arg * arg);

	square(1, 2, 3, 4, 5); // => [1, 4, 9, 16, 25]

Using the ..spread operator gives us a proper array from the start and lets us stop using the arguments object.

We can convert arguments to a proper array with Array.prototype.slice and then we can iterate over it.

	var square = function() {
	var args = Array.prototype.slice.call(arguments); // convert arguments to array.

	return args.map(function(arg) {
	return arg * arg;
	});
	};

	square(1, 2, 3, 4, 5); // => [1, 4, 9, 16, 25]

Arguments is an "array like" object so you cannot directly iterate over it.

	var square = function () {
	return arguments.map(function(arg) {
	return arg * arg;
	});
	};

	square(1, 2, 3, 4, 5); // => "TypeError: arguments.map is not a function
