Description from the creator

In this video I'll be showing you how to use the powerful MutationObserver in JavaScript which let's you watch for changes in the DOM tree.

Using the MutationObserver you're able to react for things like when an elements attribute or text changes as well as when nodes have been added or removed from a parent node/element. In this video I'll be covering a few examples of how to do those things.
