This next example, in Clojure, consumes three asynchronous Observables, including a dependency from one to another, and emits a single response item by combining the items emitted by each of the three Observables with the [`zip`](http://reactivex.io/documentation/operators/zip.html) operator and then transforming the result with [`map`](http://reactivex.io/documentation/operators/map.html):

The following example, in Groovy, comes from [Ben Christensen’s QCon presentation on the evolution of the Netflix API](https://speakerdeck.com/benjchristensen/evolution-of-the-netflix-api-qcon-sf-2013). It combines two Observables with the [`merge`](http://reactivex.io/documentation/operators/merge.html) operator, then uses the [`reduce`](http://reactivex.io/documentation/operators/reduce.html) operator to construct a single item out of the resulting sequence, then transforms that item with [`map`](http://reactivex.io/documentation/operators/map.html) before emitting it:
