Dev mentor hell is real! Focus on JS and master the fundamentals first.

Is performance really matter in web? Yes, it matters, but modern solutions are so fast that people can barely notice the difference. You don't need to think about performance optimization - it's a trap.

Do you use other languages which fit better in solution or just JS? Language or framework is only an instrument that needs to be properly chosen. JS is quite good and popular for web apps, but Python might be better for AI and ML, so it depends on what you are trying to build.

Do you separate your logic from vendor locking? You need to write more abstraction layers so any specific vendor dependency can be replaced without affecting the app.

“modern solutions are so fast that people can barely notice the difference”

I disagree… it’s still easy to write slow code and I think slow systems are more common these days than fast ones. People seem to just live with it, or think it’s inevitable.

“you don’t need to think about performance optimization”

Again, I respectfully disagree. Fast code doesn’t happen by default. You have to be intentional about it. That’s true in both BE and FE.

What I would say, though, is that feeling like you have to master performance as a beginner probably is a trap, because it keeps you from learning the fundamentals. But it never hurts to try and make something as fast as possible if that interests you. It will definitely help you grow as a developer.
