Elm and game development, a perfect fit
summary
Uses Elm and its Elm architecture plus subscriptions/time.every to build a working Flappy Bird clone that generates pipes every two seconds, handles keydown events with key codes, detects collisions, and posts scores for a live scoreboard (with optional sockets). Shows why explicit state — an update function that receives messages and the current state and returns the next state — maps cleanly to game loops, and demonstrates a concrete, playable web game rather than abstract examples.
