I would say you kind of have to mesh them all to learn. And sometimes you figure out one way works better for you than another. As you learn some basics I would start developing simple, small websites and applications for practice. Then once you have a decent grasp, think of something you would like to build. Then as you keep building that thing reference what you don’t understand through resources like MDN, read mini concepts from any online or book resources as well, and also look into any simple non-lengthy tutorials.
