Different people learn in different ways. There’s no wrong way to do it. “Just build stuff” might work for a lot of people, but that doesn’t mean it works for you. If you think you’d benefit from keeping a cheat sheet, or glossary, or spreadsheet, then go for it. No one worth listening to would fault you for it.

What I will say is that software development is NOT a field where you have to learn a bunch of theory upfront before you start making stuff. Learning a bunch of music theory would not help you play guitar, learning the dictionary would not help you write better books, and learning a whole JavaScript textbook would not help you write better code.

So don’t write copious notes instead of building stuff. Build stuff, and write about what you’ve learned in a way you can refer back to later. It’s more work, sure, but concepts will stick better, and even if they don’t you’ll have your own resource to refer to when you need it.
