While there aren't any major surprises here, it's interesting to note that Server Components and Server Functions are the third and fourth most disliked features respectively, which is troubling for a set of new APIs that was supposed to pave the way towards React's next big evolution towards a more complete full-stack framework.

Main APIs Over Time

React is a mature library, and that translates into fairly predictable usage curves for its main APIs.

When it comes to hooks, useId has been gaining adoption quickly. And while useEffect is still one of the most-used hooks APIs, it's also the one with the lowest satifaction ratio, confirming many developers' issues with the hook's finicky reactivity model.

New APIs Over Time

While Server Components and Server Functions are both slowly growing in popularity, Suspense is the new feature with the highest adoption rate.

It also boasts a high satisfaction ratio, which sadly isn't the case for the aforementioned server APIs.

The <ViewTransition> API may still only be available in React Canary, but it's already generating a lot of curiosity among respondents, along with <Profiler>.
