Graduate experimental N-API feature napi_threadsafe_function #24249
Description
I reworked fsevents to use N-API. For that I had to use the napi_threadsafe_function family of features, which are currently behind experimental. They work like a charm.
Can we graduate these out of experimental, backport them to v8.x and bump the N-API version?
