$timeout
service in module ng
Description
Angular's wrapper for window.setTimeout. The fn function is wrapped into a try/catch block and delegates any exceptions to $exceptionHandler service.
The return value of registering a timeout function is a promise, which will be resolved when the timeout is reached and the timeout function is executed.
To cancel a timeout request, call $timeout.cancel(promise).
In tests you can use $timeout.flush() to synchronously flush the queue of deferred functions.
Dependencies
