Array.length will give you the number of top-level elements in an array.

Your task is to create a function deepCount that returns the number of ALL elements within an array, including any within inner-level arrays.

For example:

deepCount([1, 2, 3]);  
//>>>>> 3
deepCount(["x", "y", ["z"]]);  
//>>>>> 4

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)
