At first, this seems counterintuitive since the value of `n` <em>decreases</em>, but the values in the final array are <em>increasing</em>. This happens because the push happens last, after the recursive call has returned. At the point where `n` is pushed into the array, `count(n - 1)` has already been evaluated and returned `[1, 2, ..., n - 1]`.
