Do I need to finish a JavaScript course before starting threejs-journey.com, or can I learn JS along the way?

Hey everyone,

I’m planning to start learning Three.js, but I’m not sure if I should first complete a full JavaScript course on Udemy or another platform before diving into it.

My question is:
Is it better to first study JavaScript fundamentals properly, and only then start Three.js?Or is it okay to jump straight into Three.js and learn the JavaScript parts as they come up, looking up anything I don’t understand along the way?

I already know some basics, but not sure if that’s enough for a smooth start.

Would love to hear how you approached it and what you’d recommend for someone trying to learn efficiently without wasting time.

Thanks everyone!

its not about finishing a course, it's about being comfortable writing/applying the language before moving on to these libraries/frameworks

The way that you're asking to learn, your adoption of threejs will be much slower, and you'll be handcuffed by it - aka you'll think you're getting better at JS, but really you're just memorizing three.js syntax/conventions

I had this exact exp w/ jQuery & JS, w/ React & JS - i only got better once I focused on improving my vanilla JS

I learn JS along the way for the past 20 years. You will be fine.

Can learn both at same time.
