[Pseudo-Pixi Question] How do I move my javascript code into its own file?

[rosenjcb]

So I have this code:

http://pastebin.com/1AFjYcSq

 

As you see, it's just an html file with some javascript code embedded into it. It works fine, but I obviously can't have an entire game's code just smashed into the html5 file. Would anyone mind explaining to me, as if I'm a complete idiot, how to link a javascript file in html5 and have it call the appropriate calls? 

 

Thanks!

Really simple, just put "<script src="path/to/file.js"></script>" in  your code
