Fun fact about JavaScript: it's a... bit inconsistent. For example, functions like Array.map, Array.reduce, Array.sort don't mutate the array, but Array.unshift does, and returns array's length after the element was added.

    Pretty sure Array.sort mutates array. The whole point of unshift is to add an element to array, there's Array.concat if you'd like to create a new array with extra elements. And how would Array.reduce even mutate an array?
