Intermediate Algorithm Scripting - Arguments Optional

JavaScript
1

Neat solution using the rest parameter syntax from ES6.

function addTogether(x, ...y) {
	if (typeof(x) == 'number') {
		if (y.length == 0) {
			// if one argument is passed
			return function(y) {
				return typeof(y) == 'number' ? x + y : undefined;
			};
		} else {
			// if two arguments or more are passed
			return (typeof(y[0]) == 'number') ? x + y[0] : undefined;
		}
	} else {
		return undefined;
	}
}
