Find the length of an Array consisting of 2D arrays
<p>Is there a way to find the length of this array, and all the sub arrays inside it. Meaning 13 and not 6? Without having to use loops and adding up all the elements inside the arrays.</p>

<p>I'm looking for one command that can do this.</p>

<pre><code>[1, [4, 5, 2, 1], 2, [4, 5, 2, 6], 2, [3, 3]]
</code></pre>
