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.
