Learning a Scripting language

I've become more interested in learning javaScript for Unity, I'm just a little confused.
Should I go ahead and buy some books teaching me javaScript, or is Unitys version of this language heaps different?
Does anyone have any recommended books, Online Tutorials or general info links they would like to share with me.
I will keep rummaging through the forums and whatnot looking for answers in the meantime but any help would be appreciated

 

Unity's version has similar syntax, but you need to be much more explicit in UnityScript. It would be easier to learn if you knew JS, but it isn't necessary. I would look at the tutorials and then look in the scripting reference to see what everything means. The tutorials give you the functions and syntax, while the scripting reference gives you the usage and the syntax.

 

If you like to have books around to randomly read go ahead otherwise there is a sea of information easily accessible from your computer.
