Great video. Your volume was oddly all over the place but I have a volume control so I adjusted. :)

This is 100% exactly what I was looking for to implement in a React project I'm working on. Thank you so much

Thank you. I am currently writing a plug-in to replace some texts. Need to use mutation observer on sites like Facebook, Twitter as their contents are dynamically loaded.

BTW To those who wants to skip directly to Mutation Observer in action - 3:10

@kyle I hope you do another one, because this is so so under talked about and you are only touching the tip I think. I'm trying to figure out how to use it for state management in a game. Check to see if the state is true (game on) and if it's false (game over). I know I know that's so basic, but the point isn't how hard, but if and how to use mutation observer to track that change. I just think it's interesting is all. Thoughts? I'm really keen to hear any (kindly worded) feedback.
