Python

Seconding the linked Khan Academy course, i taught a class for a few years that followed those lessons. The lessons are a little outdated, but they’re perfectly suitable for learning fundamental JS syntax.

The visual aspect, imo, is super helpful when first learning. Being able to see the results of your code makes understanding what’s happening way easier. Additionally, those lessons provide hints and friendly reminders to help with syntax errors.

Those lessons in particular use a JS library called P5.js if you want to play around with it outside of the Khan Academy environment. More than enough for making a simple game, and the documentation is pretty great too.
