> If you’ve ever profiled a React app – even in production mode – you know there is a non-negligible performance impact to every component that renders.

Maybe it's just me, but I've used React for ~5 years and I've never needed to profile an app, since the performance out of the box has always been good enough.

The situation is much more severe with react-native, which doesn’t have a JIT compiler available.
