title: Capture line only if there is no numbers
body: <p>Basically I am trying to write a regex in Javascript that looks for a certain string, but I don't want it to match if that string contains a number. It is hard to explain so an exmaple will be better.</p>
  
  <p>String:<br>
  Blah blah blah<br>
  Blah 233 blah<br><br>
  Match: Blah blah blah<br>
  Don't Match: Blah 233 blah</p>
  
  <p>I have tried negative lookaheads, and other means to get it to work but it is beyond me on how I would get it to work as I am very inexperienced with regex.</p>
