Hey everyone! I've recently realized that I've been making a mess of my code by putting all my variables at the top of my files whenever I need to reference elements multiple times. This results in a really long list of variables, which gets confusing as the code grows. I'm starting to think that this might not be the best practice, and I'd love to hear some advice on how to manage this better. What are some effective strategies to avoid having a wall of variables? Thanks for any tips! 😊

For basic JavaScript projects, I think it's okay to have a handful of variables, but you don't want to end up with a massive list. As your project grows, you’ll need to start modularizing your code. At that point, using a framework can really help you break everything down into smaller components. But for now, if it's manageable, keep doing what works for you!
Have you looked into the concept of scoping? It's super important! Setting variable scope properly can help you avoid that wall of variables. When you declare variables inside functions or specific blocks, they only exist there. This helps keep things organized and easier to manage!
Are you using any tools to package your JavaScript? If not, you should try Parcel! It's great for splitting code into multiple files and keeping your modules more organized. It could really help you out!
I'll definitely check that out! I do use Svelte components, but they get a bit too big sometimes.
It sounds like you're just starting out with programming! Definitely check out some resources on software design and coding principles like DRY (Don't Repeat Yourself) and SOLID. Try to use modular design and break your code into multiple files. Move variables to functions or classes where they make sense instead of using a bunch of globals. It’ll help a lot as you progress!
Not really familiar with it, but I want to learn!
