How powerful is JavaScript in Unity?

Question

JavaScript

I plan to learn Unity in a while. As far as I understand, there are currently two supported languages ​​- JS and C#.
There is no particular desire to learn C # from scratch. Is it possible to do with one JS?
There is also a kind of JavaScript modification - are they very different?

Answer 1

currently there are two supported languages ​​- JS and C#.

UnityScript and C#.
The first language is only marginally different from C# and bears little resemblance to JS.

There is no particular desire to learn C # from scratch. Is it possible to do with one JS?

Maybe then it’s even easier for a waiter to shout “free cash”?
Learning C# against the background of the total amount of knowledge that you have to learn is a mere trifle.

There is also a kind of JavaScript modification - are they very different?

Strongly. There are many more similarities with C#.

Answer 2

For Unity3D - only C#!
No JS and the like!
