Blizzards spell codes

[koala]

does anyone know if blizzard has published jass codes of their abilities (if that's possible and they may exist), when yes where can I find them?

Every spell, item, unit, etc. has a four letter code. To see this, go into Edit > Display Values as Raw Data.

I know this with the 4 letter code, but this code must tell the game how to use the spell, right? and I wanted to know what does it tell the game (if there's a jass script or something else, to look it up in the mpqs)
