" summary

Clear claim: functional reactive programming equals reactive streams combined with functional operators, demonstrated with rx Java and observables. Concrete examples show an observable light switch feeding a light bulb via map to convert states and combineLatest to merge team and board streams for a Trello-style UI. Marble diagrams and operators are used to handle asynchrony and modularity, and wrapping legacy listeners into observables proves the approach works for Android and web integrations.
