Jesse Tomchak shows viewers how to use the new React compiler to automate memoization and useCallback to optimize React components. He demonstrates the manual process of optimizing React code and then shows how the React compiler simplifies this by automatically managing these optimizations. He also demonstrates setting up and configuring the compiler in React v18 using a Babel plugin, and explores the generated output to explain how the compiler enhances performance.
