Marc Backes presented this talk at Vue.js Live 2023 in London: "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'."
