*preferably something that's not just the basic stuff bc i already know that

You can try theodinproject.com

I got certificates on freecodecamp.org so I can plan my personal projects and develop them myself but if you don't want basic stuff, maybe try scrimba.com

I tried exercism.org and idk if it's basic enough for you to not try

i started with freecodecamp & Odin Project! this book helped me a lot at the beginning too: a smarter way to learn javascript - you can probably find a pdf of it online

tbh as the fullstack developer college student, if you want to be a frontend web developer, you should develop projects that you use JavaScript frameworks like React, Vue and Angular (that means you'd also write TypeScript)

and check out React, Vue, Angular official sites for tutorials

Codecademy has some interesting free courses on frontend frameworks. Net ninja on YouTube is also a great place to learn new tools

that's super exciting you're gonna kill it!!! i agree with @devhank that if you're considering it as a career, learning modern frameworks would be really important. along with what they recommended id throw in some backend too like databases and server stuff like express.js, node.js.

got it, i wrote down all the tips and sites, thanks y'all, this helped me a lot to figure out where to start!!
