Promise pending is -------------- when the operation terminates with an error. fulfilled. rejected. queued. asynchronous.

A promise is said to be settled if it is either fulfilled or rejected but pending. True. False.

Once a Promise is fulfilled, the respective handler function onFulfilled will be called asynchronously. True. False.

Once a Promise is rejected, the respective handler function onRejected will be called asynchronously. True. False.

If a handler function returns a value, the promise returned by then gets resolved with the returned value as its value. True. False.

The Promise returned by catch() is rejected if onRejected throws an error or returns a Promise which is itself rejected. True. False.

One of the property of then() method is that it synchronously returns another promise which allows us to bind chains of promises. True. False.

In validation template driven forms, --------is true if the user hasn’t changed the value, and false if the user has. touched. pristine. dirty. invalid.
