summary

Shows that expressing code as pure functions and using higher-order functions like Map, Reduce, and Filter avoids side effects, with a concrete example replacing a room via rooms.map instead of mutating the array. Explains structural sharing and persistent data structures (Bagwell → Hickey/Clojure) to avoid full-copy inefficiency, demonstrates the tree-based reuse idea, and points to practical tools such as Mori and Immutable.js (also Ramda, Lodash).
