Are JavaScript and C# Good enough for Simple Unity Project Scripts?

Answer 1

C# is, yes.
You will need to get used to Monobehaviour and the Unity Engine library regardless.

Javascript is a bit different in Unity, it's more like a hand up version that tries to pretend to be Javascript. I say this because you will still be dealing with classes (although they are kind of hidden), data-types, semi-colons (required), privacy etc..
I suggest sticking with C# for Unity, but feel free to try the Javascript as it may be easier for the programmer.
