We need 10x faster TypeScript IntelliSense instead of 10x faster bundling. This is a real improvement for the world. :p

The PR is here 💁♂️
github.com/vuejs/core/pull/1…
The main capabilities required by Vue have been completed, and the performance remains at ~400% of Vue 3.4 and ~180%(normal cases) / ~6500%(large case) of Vue 3.5.

A point not mentioned in the Vue 3.4 blog:
Vue 3.2 had already optimized the performance of the reactivity system, enhancing the scheduling performance several times over.
However, the reactivity system in Vue 3.4 has been rewritten, making it several times faster than Vue 3.2. As a result, the reactivity system in Vue 3.4 is even 1000% to 2000% faster than Vue versions 3.1 and below. 😁

Looking back at the past 6 months, my work has been almost entirely performance-focused:
- alien-signals
- DefineComponent rewrite
- Vapor Mode speed boost
- Vue Language Tools v3
I feel incredibly lucky – each of these tasks carried significant risk of failure!

We are adopting it in the Volar repo. I will be experimenting with this project for a few months before formally introducing it to you.
Especially for TS linting, current solutions have too much repetitive work and runtime overhead. I'll probably start a new project by the end of this year to explore a completely different solution.
