title: Converting a comma separated string into an array
body: <p>I have the following string:</p>
  
  <pre><code>'"alpha", "beta", "gamma", "delta"'
  </code></pre>
  
  <p>How can I convert the string into an array such that:</p>
  
  <pre><code>array = ["alpha", "beta", "gamma", "delta"];
  </code></pre>
  
  <p>So I can call on individual elements of the array such that:</p>
  
  <pre><code>array[0] = "alpha"
  </code></pre>
  
  <p>I've attempted using str.split but am unsure of the correct usage to separate the quotation marks and commas.</p>
