Step 1 — Modern JavaScript

Before touching React Native, be comfortable with functions, arrays, destructuring, promises and modules. The Modern JavaScript Tutorial (javascript.info) covers all of it free.

Step 2 — React fundamentals

React Native is React. Work through the official react.dev tutorial until components, props and state feel natural.

Step 3 — Your first app with Expo

Expo removes native tooling pain. The official Expo tutorial gets a real app on your phone in an afternoon.

Step 4 — A full course

Pick one: Mosh's React Native tutorial for a quick tour, or CS50's Mobile App Development for depth and a certificate.

Step 5 — Build and publish

Clone a simple app you use daily — a habit tracker, a notes app — and take it all the way to a store listing. Shipping teaches more than any lecture.
