Bizzarre, I use it most client-side. Anyway, where you use it doesn't really count: are you proficient with it (or feel like it, I'm not putting up myself as a big expert :) )?
To be clear: I'm looking around in case the theme inspires me, and looking forward to make a pure javascript (plus threejs if 3D) game. So I'm asking just in case here and there
I don't even have (recent) experience in coding anything in vanilla js. Also, since i'm totally new to this, I really wanted to go for something that's completely different to what I'm doing now which is why I'm trying to learn Godot.
