title: How to count the number of arrays in a nested array
body: <p>I want to count the number of arrays in the nested arrays of an array</p>
  
  <pre><code>array = [[["-", 0, "I"], ["+", 0, "you"]], [["+", 3, "i"]], [["-", 4, "loved"], ["-", 5, "that"], ["+", 5, "it"], ["+", 6, "tasted"], ["+", 7, "like"]]]
  </code></pre>
  
  <p>This example would have 8 nested arrays inside the arrays in the <code>array</code> array. (not sure if I worded that right)</p>
