Summary from the TLDR Web Dev newsletter

One of the best ways to reduce lag in Expo apps is by focusing on JavaScript performance and thread management. Modern JavaScript features like TypeScript and ESM syntax, with tools like ESLint for React rule enforcement, help make code more efficient. React Compiler also adds for automatic memoization and optimization. For advanced optimization, using React 19's `use` API and multi-threading with Reanimated worklets for complex animations are good options to explore.
