In a unit, is it critical to write a game in C # or in JS?

Question

Unity

Tell me, is there any difference, except for the syntax, in what language in the unit to write the game?
What will be the output?

Answer 1

The output will be what you write. There will be no output difference.
But inside - will be. Because there is no JS in the unit in the first place - it has its own language, JS-like, and secondly, it is not normally supported anymore. Write in C#.
