Purge all $watch instances in AngularJS before $destroy event

Is there a way to easily deregister all watchers on a scope with one simple command? I have multiple $watch functions on my scope, each returning its own deregister function. Instead of saving and calling each watcher individually, I want a method to automatically deregister all watchers when the scope is destroyed.

Would it be possible to utilize the $$watcher attribute present in the scope for this purpose?

Answer №1

Essentially, when the scope broadcasts `$destroy`, it indicates that the `scope` has triggered the execution of its own `$destroy()` method. This results in the clean up of everything associated with that particular scope, including the `watchers`. Referencing this section of the source code provides insight into how the `$destroy()` method clears out the watchers linked to that scope.
