Twitter recently switched all of their mobile web front-end users to a modern, JavaScript-based web stack. In doing so, they demonstrated how advancements in mobile web technologies rival the performance of native-based apps.

The “new” web stack has actually been in production for over 9 months for those logged-in users. Logged-out users were actually served by a different stack comprised of Scala and Closure Templates.
