title: Looking to trim a string using javascript / regex
body: <p>I'm looking for some assistance with JavaScript/Regex when trying to format a string of text.
  I have the following IDs:</p>
  
  <pre><code>00A1234/A12
  0A1234/A12
  A1234/A12
  000A1234/A12
  </code></pre>
  
  <p>I'm looking for a way that I can trim all of these down to <code>1234/A12</code>. In essence, it should find the first letter from the left, and remove it and any preceding numbers so the final format should be <code>0000/A00</code> or <code>0000/AA00</code>.</p>
  
  <p>Is there an efficient way this can be acheived by Javascript? I'm looking at Regex at the moment.</p>
