well that's any framework with vdom, the GC of web frameworks, so I'd imagine it's also a problem with vue etc..

I don't understand though why performance (I.e. using it properly) is not a consideration with these companies that are valued above $100 billion

like, do these poor pitiful big tech companies only have the resources to do so when they hit the 2 trillion mark or something?

Vue uses signals for reactivity now and has for years. Alien signals was discovered by a Vue contributor. Vue 3.6 (now in alpha/beta?) will ship a version that is essentially a Vue flavored Svelte with extreme fine grained reactivity based on a custom compiler step.

One of the reasons Vue has such a loyal community is because the framework continues to improve performance without forcing you to adopt new syntax every 18 months because the framework authors got bored.

It's not a problem with vue or svelte because they are, ironically, reactive. React greedily rerenders.

It's also not a problem with the react compiler.

Nobody gets promoted for improving web app performance.

yep. I think this is the root problem, not the frameworks themselves

If it's slow people also stick around for longer if they have something they must accomplish before leaving.

I think linkedin is built with emberjs not react last i checked…

The problem with performance in wep apps is often not the omg too much render. But is actually processing and memory use. Chromium loves to eat as much ram as possible and the state management world of web apps loves immutability. What happens when you create new state anytime something changes and v8 then needs to recompile an optimized structure for that state coupled with thrashing the gc? You already know.

I hate the immutable trend in wep apps. I get it but the performance is dogshite. Most web apps i have worked on spend about 10% of their cpu time…garbage collecting and the rest doing complicated deep state comparisons every time you hover on a button.

Rant over.
