title: Using regular expressions to locate line comments without spaces
body: <p>I tried to find all comments beginning with <code>//</code> that don't have a space after the slashes.<br>
  I want to select <em>only</em> the slashes. No whitespace or text before that, no whitespace or text after that.<br>
  So far I've reached to <code>[\s].(\/\/(?! ))</code> but it catches the space before the slashes as well.</p>
  
  <p>Basically I wanna make sure my line comments have a space after the slashes.
  I'm trying to do this either in JavaScript or in any text editor.</p>
