Can you explain? AFAIK Godot uses C++ under the hood which does not have garbage collection. Other languages such as C# and GDScript use bindings.

Most people using Godot will be using GDScript or C# to make their games.

Funnily enough whilst trying to Google gdscript and godot, I found this post I wrote in 2018 (subcomments mention gdscript and gc).
