In this video Iftach Bar shows what happens when you have a watch leak, how to avoid it, and how to manually destroy a watch.
- Watchers should be destroyed…when they are no longer needed.…The watchers are costly.…They make the digest look slower,…which makes the whole app slower.…We will talk about the digest look later on in the course.…Sometimes we might want to stop a watcher…because it make sense in their application.…In this video, we'll learn when watchers…are being destroyed and how we can manually destroy them.…Notice, that when we use the $watch function,…we use it on a certain scope.…
I'm going to remove it from app.js as well.…I'll remove the whole watch statement here as well.…
