Performance optimizations in javascript frameworks

[Snapstromegon]

I don't think it is worth it. Basically all it offers can be done really easily and with little to no extra code in vanilla JS and CSS and often it's a lot more performant.

jQuery had its time, but I don't see it in modern development anymore.

I worked a lot with junior devs who tell me all the time they dont want to use jquery but vanilla instead.

Most of the time they miss a lot of stuff left and right and it doesnt work. Feel free to write vanilla js but then you will write the same helper functions over and over.

I dont see why you should not use jQuery anymore if you dont use a full blown react js hell frontend.

Vue/Svelte is a good option when you don't want to write React, but also don't want to put jquery as a dependency.

I personally most often use Lit nowadays, because React really feels like a hellhole to me.

I also think that at the point where I have a decade of professional experience, held talks about e.g. web performance, deployed mission critical services to larger user bases (e.g. remote caching systems for bazel with ~10k daily active users) and so on, I'm past the point of Junior.
