Description

The "Introduction to React Native" entry in courses/free-courses-en.md (React Native section) points to https://fullstackopen.com/en/part10/introduction_to_react_native, which now returns HTTP 404. Full Stack Open moved part 10 to MOOC.fi: its own course info page (https://fullstackopen.com/en/part0/general_info) says "Material of part 10 has been moved to https://courses.mooc.fi/org/uh-cs/courses/full-stack-open-react-native".

• Old: https://fullstackopen.com/en/part10/introduction_to_react_native (404)
• New: https://courses.mooc.fi/org/uh-cs/courses/full-stack-open-react-native (200), the location the course authors link to
• Added (MOOC.fi) as the platform, per the "Platforms and Access Notes" section of CONTRIBUTING.

The other fullstackopen.com links in the file (/en/, /en/part1/introduction_to_react) still return 200, so they are unchanged.

Why is this valuable (or not)?

Readers currently land on a 404 instead of the course.

How do we know it's really free?

Same free University of Helsinki course as before; only its host changed.

For book lists, is it a book? For course lists, is it a course? etc.

Yes, a course.

Code Review

LGTM!

• Link Verification: Verified that https://courses.mooc.fi/org/uh-cs/courses/full-stack-open-react-native returns HTTP 200 OK and matches the official University of Helsinki / Full Stack Open migration note.
• Alphabetical Order: Proper alphabetical sorting within the React Native section is preserved (Introduction to React Native sits correctly between CS50 and React Native for Beginners).
• Formatting Guidelines: Appending the platform attribution (MOOC.fi) aligns with the guidelines in CONTRIBUTING.md.

Ready for merge!
