Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/36314 ## Changelog: [Internal] - Added support for W3C Performance API extension (Performance,getEntries*) See [here for the details](https://www.w3.org/TR/performance-timeline/#extensions-to-the-performance-interface). This only supports `mark` and `measure` performance entry types (not `events`, as those are not supported by browsers either, they recommend using the `PerformanceObserver` API instead). From the implementation perspective, we already maintained persistent buffer for `mark` entry types, which was required in order to look up measures. The buffer is circular, limited to 1K entries by default. I basically mimic the same behavior for `measure` entry types as well, since it's the simplest way of doing it at this point, If we happen to want adding some other entry types that would be available via `Performance.getEntries*` API in the future, we may want to iterate on the internal data structures representation inside `PerformanceEntryReporter`, but for now I believe this approach should work just fine, and whatever changes we may want to do will be purely internal implementation detail.
