Web development can be tough. DOM APIs are known to be inconvenient, and you often build the same things over and over again. Thanks to rolling releases by browser vendors this changed. Development of the web as a platform has sped up like never before. New APIs land in browsers with every release allowing for "reactive programming" through new Observer and Observable APIs.

Looking for a way to detect DOM changes to update a different part of the page? MutationObserver got you covered. Want to get notified when elements enter the viewport to load assets? IntersectionObserver is your friend. Are you dealing with sequences of events over time and want to save yourself some headaches? Observables will make your life way easier.

Join Stefan for this talk as he covers the use cases of Observer/Observable APIs, go over implementation details, and cover everything you need to know to use them in production.
