title: Extract arrays of characters in String in Javascript
body: <p>I've looked around and practiced my RegEx but I still can't get it right... Probably a noob question
  How would I split a string to only keep the words (a to z) and only them, split by any other character?</p>
  
  <pre><code>hello3you ?! hey 32 foo
  </code></pre>
  
  <p>would return</p>
  
  <pre><code>["hello","you","hey","foo"]
  </code></pre>
  
  <p>I tried the following, no luck:</p>
  
  <pre><code>var words = itemObject["name"].toLowerCase().split(/^([a-z]+)/g);
  var words = itemObject["name"].toLowerCase().split(/[a-zA-Z]+/g);
  </code></pre>
  
  <p>Thanks</p>
