import { sequenceEqual as higherOrder } from '../operators/sequenceEqual'; /** * Compares all values of two observables in sequence using an optional comparor function * and returns an observable of a single boolean value representing whether or not the two sequences * are equal. * * Checks to see of all values emitted by both observables are equal, in order. * * * * `sequenceEqual` subscribes to two observables and buffers incoming values from each observable. Whenever either * observable emits a value, the value is buffered and the buffers are shifted and compared from the bottom * up; If any value pair doesn't match, the returned observable will emit `false` and complete. If one of the * observables completes, the operator will wait for the other observable to complete; If the other * observable emits before completing, the returned observable will emit `false` and complete. If one observable never * completes or emits after the other complets, the returned observable will never complete. * * @example figure out if the Konami code matches * var code = Rx.Observable.from([ * "ArrowUp", * "ArrowUp", * "ArrowDown", * "ArrowDown", * "ArrowLeft", * "ArrowRight", * "ArrowLeft", * "ArrowRight", * "KeyB", * "KeyA", * "Enter" // no start key, clearly. * ]); * * var keys = Rx.Observable.fromEvent(document, 'keyup') * .map(e => e.code); * var matches = keys.bufferCount(11, 1) * .mergeMap( * last11 => * Rx.Observable.from(last11) * .sequenceEqual(code) * ); * matches.subscribe(matched => console.log('Successful cheat at Contra?
