title: Deleting specific array element from multidimensional array?
body: <p>I'm having trouble cycling through a multidimensional array and deleting a specific element array. My multidimensional array looks a little like this: </p>
  
  <pre><code>myArray = [["Tom", "161"], ["Dick", "29"], ["Harry", "46"]];
  </code></pre>
  
  <p>So if I have the number 29. What's the most efficient way to cycle through this array and delete the array element who's second element is 29? i.e. ["Dick", "29"]</p>
