Oh Composable World!
summary
Claims that dot chaining equals function composition and shows how map chain concat handle the three biggest complexity sources (state control flow code volume). Uses plain JavaScript: arrays, a single-value Box with map and fold, lazy promises with Fork to defer side effects, Either for branching, map/filter/reduce and unfold for loops. Builds and demos a composed React app (recompose/Redux-style reducers) that actually runs and shows adding todos, so the approach is practical not just theoretical.
