React Native
React components on native views. Share logic with web until platform differences ruin your sprint.
React Native stuck because web teams could ship mobile without learning two platform religions. Bridge pain and upgrade churn are real taxes. Still cheaper than twin native teams for many product shapes.

Context
Frameworks fought for the runtime
Front-end frameworks consolidated power; TypeScript became the floor; serverless and Jamstack rebranded old ideas with better CDNs. Blockchain-for-CRUD and big-bang rewrites collected the decade’s dumbest budgets. The winners were boring platforms with ecosystems. The losers were narratives that skipped product-market fit.
