title: Is parseInt() supposed to work like this?
body: <p>If I write this script :</p>
  
  <p><code>alert(parseInt("123blahblahblah456"));</code></p>
  
  <p>I get the alert with the value <code>123</code></p>
  
  <p>Ideally, shouldn't the function NOT do anything since it is an invalid integer string?
  Similar is the case with <code>parseFloat()</code></p>
