Elm Town 80 – Inspired: Roc with Richard Feldman

Elm Town

Elm pioneer Richard Feldman returns to explain why he made Roc, a direct descendant of Elm. He notes a distinct trade-off of choosing not to have persistent data structures. Later, he shares how his experience teaching Elm informed Roc's design. We even learn about the power of platforms.
