Hi WebKittens, I've landed the update of the ES6 Promise implementation. Through this work, I've experimentally added the internal private function, @enqueueJob(JS function, JS array for arguments). This is corresponding to the ES6 spec EnqueueJob[1].
This EnqueueJob handler is now tightly integrated with WebCore's microtask infrastructure. So in JSC framework side, we cannot use this function. As a result, current JSC framework disables Promise because there's no event loop abstraction. So I propose the API configuring euqueueJob handler into JSC VM (That corresponds to the Realm in ECMA spec). Like, void JSContextGroupSetEnqueueJobCallback(JSContextGroupRef, JSEnqueueJobCallback, void* callbackData); What do you think about this?
