In this episode of JavaScript Jabber, I sat down with Shruti Kapoor, independent content creator and longtime React educator, to dig into what’s actually new — and worth getting excited about — in React 19.2. While it may sound like a “minor” release on paper, this update delivers some genuinely powerful improvements that can change how we build and reason about React apps.
We talked through React Compiler finally becoming stable, how the new Activity component can dramatically simplify state management and UX, what View Transitions mean for animations, and why new tooling like Performance Tracks in Chrome DevTools is such a big deal for debugging. If you care about performance, async React, or writing less code with better results, this one’s for you.
