I really liked the pace of the video you do not waste time on nonsense and you manage to take complicated topics and simplify them so that it is really easy to understand you

Thank you very much Kyle! Earlier I was working on a todo list application and I used an event listener to listen for things with the contenteditable attribute to change to rename the todos. I used the DOMCharacterDataModified event listener. But then I learned that was going to go out of support very soon for Mutation Observer. I didn't know that really confusing thing with the text content being a node, and i was so frustrated. Thank you very much for this!

I ended up using the input event listener tho.

I've been using it for years. Basically any use-case where you want to detect changes in your DOM, you can easily do using MO.
