What Should I Learn Next in JavaScript for My Project?

Learning with vanilla JS is a fantastic choice! For your project, you can definitely use JSON files instead of a database; that's a great way to keep it simple. Just create a module for your data and import it where needed.

As for architecture, focus on making your functions small and single-purpose. If something feels too complicated, break it down. You'll find that learning this way is more intuitive than getting caught up in debates over OOP vs. functional programming.

Regarding books, I'd suggest reading MDN docs cover to cover; they're dry but incredibly informative. Get "JavaScript: The Good Parts" when you're ready for a shorter read. Understanding concepts like event delegation and the event loop will really demystify frameworks like React and Vue for you!

Real projects are the best way to learn! Try seeking out small tasks or freelance gigs that push you to develop your skills. If you can, working on something with a client can elevate your learning experience dramatically.

Database-wise, Postgres is powerful and worth exploring, but for your current project, sticking with JSON is perfectly fine!

You may want to check out "You Don't Know JS" by Kyle Simpson and "The Hard Parts of JavaScript" by Will Sentance. Both courses are excellent and have really helped me grasp the complexities of JS. Also, keep exploring blogs and resources as you learn; they can provide invaluable insights into best practices! You seem to be trying to absorb a lot at once, so pace yourself to avoid getting overwhelmed.

Wes Bos has a great JavaScript course that could enhance your skills while focusing on practical applications of plain JS. It's perfect for gaining confidence and solid fundamentals before jumping back into frameworks later!
