GDScript is basically Python syntax with some sugar.

* Well known: Python is well known. GDScript is thus familiar. * Well supported: it's a first class citizen in Godot, that's all that matters * Easily portable: portable to what? it runs on the Godot engine. That's all the portability it needs.

I think they built their own language because of the integration with their Editor. It's not Lua or JavaScript or Python, but it works well enough for Godot in my experience.
