React 18 Concurrency, Explained
Monday, 5th – 12:15
React 18! Concurrent features! Perhaps you’ve just heard about this release. Or maybe you’ve already tried the new APIs like useTransition. But do you know how React 18 achieves the performance wins it brings with itself?
In this talk, let’s peak under the hood of React 18’s performance features:
- How React 18 lowers the time your page stays frozen (aka TBT) and how Chromium 87 helps in this

- What exactly happens in the browser when you run useTransition()
- And why Vue and Preact straight refused to ship anything similar
- On the web
