title: How to #include in javascript?
body: <p>Say my javascript scripts <strong>aren't embedded in html/xml</strong>... I want to write a small library of helper functions to use in my scripts. Obviously there has to be an "#include" or "require" keyword in javascript, but I can't find any. Anything I could with Google relies on the code being part of html/xml, which doesn't help in my case. 
  What should I do?</p>
