is there any good place to learn javascript for unity

Try here.

Do not go on a website not-related to Unity, their javascript won’t have anything to do with UnityScript

Amazon look up unity scripting there will be several books that you can buy to help you learn unity scripting .

Got you a good starter tut here: It’s on my dropbox but it’s not mine

Here you go!

I’d highly suggest following the tutorials and looking through their scripts. I find the best way to learn scripts is to dig in and look how they run and change simple variables to see how it works. There are tons of Unity tutorials, even available on the unity3d website.
