Return more than one value

In this video, Dave mentions that a return value must be a single item (a variable, string, number, Boolean), but in his his final example he returned multiple items:

function getArea(width, length, unit) { var area = width * length; return area + " " + unit; } console.log(getArea(10, 20, 'sq ft'));

Isn't he technically returning three items? (variable, string + parameter)?

This I think is one of the downsides of JavaScript as a language. Integers like area can be concatenated with strings. It's not a stick to one data type.
