Start at the beginning: the importance of learning the basics - localghost
I’d recommend going in the order HTML, CSS, JS. That way, you can build something in HTML, add CSS to it as you learn it, and finally soup it up with your new-found JS knowledge.
Excellent advice for anyone new to web develoment.
Once you start getting into interactive website territory, with API calls and fancy stuff, that’s where you need JavaScript (JS) knowledge. More specifically, vanilla JS: plain JS with no additional frameworks or plugins. The JS that your browser understands without having to do any pre-processing. It makes working with frameworks a whole lot easier, and it’ll help you to know when not to use a framework (and avoid making users download massive JS bundles when all you need is a tiny bit of code).
