## Description

React’s new compiler is redefining performance optimization, eliminating the need for manual techniques like React.memo and useMemo. This talk takes a deep dive into how the compiler works under the hood, its impact on component rendering, and how it automates performance gains without extra effort from developers. We’ll explore its potential, current limitations, and what this means for the future of React applications. Whether you're building new projects or optimizing existing ones, you'll walk away with a clear understanding of how to leverage this cutting-edge tool as it evolves.
