Is the Virtual DOM pure overhead? In this tech talk, Aiden Bai explores the performance implications of the Virtual DOM in frameworks like React and presents an alternative approach called the \"block virtual DOM.\" Aiden delves into the origins of the Virtual DOM, its purpose in addressing performance issues, and the process of diffing and reconciliation. The talk introduces the Block virtual DOM, which takes a different approach to diffing by using static analysis and dirty checking.

The virtual DOM is generally regarded as a necessary evil, a performance tax that we have to pay for the convenience of declarative UIs.Until now.In this talk, we'll take a deep dive into what the block virtual DOM is (an new, innovative approach to VDOM), and how Million.js can help you improve the speed of your React applications. This talk will also provide a helpful overview of how the React virtual DOM works. By the end of this talk, you'll have the knowledge to not only start improving your React apps' performance with Million.js, but understand the underlying internals that make it so fast.
