title: RegExp that match everything except letters
body: <p>I'm trying to write RegExp that match everyting except letters. So far, I've wrote something like this:</p>
  
  <pre><code>/[^a-zA-Z]+/
  </code></pre>
  
  <p>However, during tests, I've found that it works nicely when I write for example: 'qwe' or 'qqqqqweqwe123123' or something similar, BUT when I start String from number for example: '1qweqwe', it doesn't match. </p>
  
  <p>What do I have to do yet to match everything except letters at any position of my input String?</p>
  
  <p>Thanks in advance.</p>
  
  <p>Edit: Correct RegExp I found is:</p>
  
  <pre><code>/^[^a-zA-Z]*$/
  </code></pre>
