   Another more useful.
   
   function $tag(tagName, from) {
   return (from || document).getElementsByTagName(tagName);
   }
   
   // $tag("li");
   // $tag("li", document.getElementById("ULID"));

   Whooo, you've just discovered aliases. Next time please try harder.

   how did this post from the past get featured? ive also got a killer javascript function:
   
   function $hello() {
   document.writeln("Hello world! I suck!");
   }

   Not only this post is a waste of time and his author presumptuous, but he also manages to get it wrong.
   
   When making an alias you DO NOT wrap it in a function ! It introduce unnecessary overhead, just keep it simple :
   
   var $tag = document.getElementsByTagName;
   
   This will do the trick and his much better than your "cross-browser implementation" of a function which as always worked everywhere...

   function $hello() {
   document.writeln("Hello world! I suck!");
   }
