This talk is designed to show people what a virtual DOM is, and what it is used for. We'll see a bit the theory of it, then build a simplified version of the Vue 3 VDOM on stage from scratch - step by step! After the talk, people will have more familiarity with the black box that sometimes is "VDOM".

Vue.js is a frontend framework. But the different modules, such as the reactivity engine can be imported on its own. Let's have some fun and explore possible use cases for Vue reactivity in the backend.
