Probably short for Godot Script, this is the scripting language godot introduced to support it's game engine.
Everyone's journey through programming languages is different - we all choose different times to start and stop.
One thing I know for sure - the more languages you use in-anger, the easier learning the next one is. I really didn't know anything about my first language or two until I learned the third or fourth.
More details to leave here, but for now, here's a rough outline of my path:
At the time of writing, my opinions are quite strongly in favor of Clojure for just about everything practical. It does so much in so little code, is extremely flexible and malleable, and is excellent for interactive debugging. Especially with the recent expansion of targets (e.g. Babashka), Clojure can reach everywhere.
I do think my path had something to do with my stability at the end. If folks come into clojure without trying to destructure json in Go, without dealing with python in anger, or without typing yourself into a category theory corner in Haskell, you might need to go chase that first.
I loved Elixir for it's simple and effective standard library and interactivity as well - Clojure just feels like an even better execution of those things.

I'm game :D
