I know javascript but i don't understand Unity's javascript!

The title says it. I learned javascript in codecademy.com I have succesfully managed to write some simple web apps and some mini-mini-games in javascript. But the real issue is, i can’t seem to understand a s*** of Unity’s javascript (unityscript i have read? correct me if wrong).I just wanted to try to make a game in unity using my javascript skills, but I can’t seem to understand what all of those class and stuff in MonoDevelop! Is there any interactive tutorial online that can help with this issue?

Its not Javascript.

Its UnityScript.

UnityScript and Javascript are two different flavors of ECMA script.
