The biggest issue, I see with learning how software works, is common names. For example, game engine. Some library or framework, that helps you to build games. Nice. But what they do for you in detail isn't known, and can take months to understand. Unity does much more than Phaser. Angular is a total different beast than React. And this goes down to class names. MVC was the hype back in the days, but nobody knows what it actually meant in detail. Some people sat down and wrote some definition of the term, but no implementer adhered 100% to them.
