title: Javascript splitting string in to two parts number and text safely
body: <p>I was wondering if there is a safe way (if the data is coming from users) to get the string and the number separated - for example "something-55", "something-124", "something-1291293"
  I would want:</p>
  
  <p>something and
  55</p>
  
  <p>something and
  124</p>
  
  <p>something and
  1291293</p>
  
  <p>I mean by a 'safe way' is to be certain I am getting only the number on the end.. if the data is coming from the users "something" could be anything some-thing-55 for example..</p>
  
  <p>I'm looking for a robust way.</p>
