Oskar Kwaśniewski kicks off the Mastering React Native TurboModules series with a practical build‑along. The example module is a simple Local Storage API: `setItem`, `getItem`, `removeItem`, and `clear`. You’ll see how the TypeScript specification drives Codegen, how the generated protocol shapes your native implementation, and how Swift + Objective‑C work together to expose a clean TurboModule surface to JavaScript. The episode finishes with an Expo test app confirming the module works as expected.
