How A Teenager Improved React's Performance

TLDRA recent high school graduate named Aiden improved React's performance by 70% with Million JS, a hyper-optimized virtual DOM that outperforms React, Solid.js, and more. A compiler in Million JS performs static analysis to accurately determine what has changed, resulting in surgical DOM updates. It's a lightweight (4KB) and easy-to-use alternative to React.
