Sorry that if the wording of the title was bad I'm only really experienced with DnD and a thing or two on coding.
I wanted to know if there are any good youtube channels, coding camps or even websites I could visit to learn more about coding.
A good basic CS class would be what I suggest, instead of something focused on GML. Everything you will learn will be applicable, and the knowledge will be much more reusable.
Python is fun and easy to start with.
I'd recommend Harvard CS50.Good point... I assumed this topic is about GameMaker because it was posted in the Programming forum on the GMC, but I may have been wrong to assume that. Re-reading the opening post, it indeed sounds like this is more about coding in general than GM. I'll move this to Off Topic, then.
In that case: I'd say where to look depends on what you want to do. "Coding" is a very broad spectrum. Do you have any goals in mind? Anything you'd like to be able to program? Any general direction of the computer science field that interests you? This would allow us to provide you with more suitable suggestions.
