- /**
- * A different implementation for monkey patching Promise.
- * Currently Zone.js patches Promise itself with ZoneAwarePromise and also Promise.prototype.then
- * The reason is:
- *
- * 1. Promise.prototype.then should trigger ZoneSpec.scheduleTask and acts as a microTask
- * 2. Promise should be able to controlled by fakeAsync(), so Promise.prototype.then can work as
- * sync operation in fakeAsync()
- * 3. Promise unhandledRejection can be handled by ZoneSpec.onHandleError hook
- *
- * And this implementation also has it's disadvantage.
- *
- * 1. We need to implement a full Promise spec by ourselves.
- * 2. We need to implement the new APIs for Promise such as (all, allSettled, any...) when the new
- * APIs are available.
- * 3. Promise behavior is different with the native one, such as the timing of then callback.
- * 4. Can not handle the some vm operation requires native Promise such as async/await or
- * SafePromise.
- *
- * And this new implementation try to address most of these disadvantages.
- * 1. We don't monkey patch Promise itself any longer.
- * 2. We only monkey patches Promise.prototype.then and schedule microTask from there.
- * 3. The Promise APIs are all using native ones.
- * 4. SafePromise issues are gone, and the timing will be the same with the native one.
- *
- * Also this new implementation introduces breaking changes.
- *
- * 1. Promise can not be easily handled by fakeAsync(), and since we will deprecate fakeAsync() in
- * the future, this is the first step.
- * 2. Promise unhandled rejection happened inside new Promise(callback) will not be handled by
- * ZoneSpec.onHandleError(thenCallback error will not be be impacted).
- *
- * So now we only introduces this change to `zone-node` bundle, since the breaking change will be
- * minor for NodeJS environment,
- * @TODO: JiaLiPassion, we will introduce this change to browser later.
