title: Regex for a word can be plural
body: <p>I want regex that will match "lead" or "leads" and will not match when it's part of another word like cheerleaders or leaders. I also don't want whitespaces matched before or after the word. </p>
  
  <p>The closet I got was <code>/(?:^|\W)Lead(?:$|\W){0,5}/g;</code></p>
  
  <p>But this matches Leaders and whitespaces. This is in javascript if that makes a difference. </p>
