title: Split string by word
body: <p>I have multiple strings assigned to variables which has a common word. How can I split these strings in to two parts from the common word?</p>
  
  <pre><code>var str= "12344A56789";
  </code></pre>
  
  <p>Instead of having to write substring multiple times, is there a way to split the string from <code>4A</code> and get the following results?</p>
  
  <pre><code>var first = "1234";
  var second = "56789";
  </code></pre>
  
  <p>NOTE: Each string lengths are different.</p>
