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.
