title: JavaScript annotations
body: <p><strong>Are there JavaScript annotations?</strong></p>
  
  <p>Of course JavaScript doesn't have them, but are there additional libraries or proposed language extension, for example</p>
  
  <pre><code>@type {folder.otherjsmodule.foo}
  function(){
      foo = folder.otherjsmodule.foo();
      ...
      return foo;
  };
  </code></pre>
