Reactivity in Vue

Join Alex and Michael on a talk about a key topic in Vue.js - the reactivity system. Before diving into how it works in Vue 3, reactivity in Vanilla JS is covered. Then, the differences between the major Vue versions are discussed, showing an astonishing evolution in terms of DX but also performance when it comes to reactivity.Of course, the ref vs reactive topic can’t be left out, and neither can signals and vapor mode.Sounds interesting? Then tune in!Enjoy the episode! Chapters(00:00) - Welcome to DejaVue (01:38) - What is Reactivity in general? (03:47) - Reactivity in JavaScript?
