If you want to learn the basics of 2D game development with PlayCanvas, the official KeepyUp tutorial will help a lot! It goes over the basics of programming 2D games in PlayCanvas, as well as other important design and art related aspects. If possible though, I would definitely recommend learning a bit of JS before you start on that tutorial, it’ll help you grasp the programming concepts much better. Traversy Media’s JavaScript Crash Course For Beginners is a great place to start.
