  * `combineLatest` combines the values from all the Observables passed as
- * arguments. This is done by subscribing to each Observable, in order, and
- * collecting an array of each of the most recent values any time any of the
- * input Observables emits, then either taking that array and passing it as
- * arguments to an optional `project` function and emitting the return value of
- * that, or just emitting the array of recent values directly if there is no
- * `project` function.
+ * arguments. This is done by subscribing to each Observable in order and,
+ * whenever any Observable emits, collecting an array of the most recent
+ * values from each Observable. So if you pass `n` Observables to operator,
+ * returned Observable will always emit an array of `n` values, in order
+ * corresponding to order of passed Observables (value from the first Observable
+ * on the first place and so on).
  *
- * @example <caption>Dynamically calculate the Body-Mass Index from an Observable of weight and one for height</caption>
+ * Static version of `combineLatest` accepts either an array of Observables
+ * or each Observable can be put directly as an argument. Note that array of
+ * Observables is good choice, if you don't know beforehand how many Observables
+ * you will combine. Passing empty array will result in Observable that
+ * completes immediately.
+ *
+ * To ensure output array has always the same length, `combineLatest` will
+ * actually wait for all input Observables to emit at least once,
+ * before it starts emitting results. This means if some Observable emits
+ * values before other Observables started emitting, all that values but last
+ * will be lost. On the other hand, is some Observable does not emit value but
+ * completes, resulting Observable will complete at the same moment without
+ * emitting anything, since it will be now impossible to include value from
+ * completed Observable in resulting array. Also, if some input Observable does
+ * not emit any value and never completes, `combineLatest` will also never emit
+ * and never complete, since, again, it will wait for all streams to emit some
+ * value.
+ *
+ * If at least one Observable was passed to `combineLatest` and all passed Observables
+ * emitted something, resulting Observable will complete when all combined
+ * streams complete. So even if some Observable completes, result of
+ * `combineLatest` will still emit values when other Observables do. In case
+ * of completed Observable, its value from now on will always be the last
+ * emitted value. On the other hand, if any Observable errors, `combineLatest`
+ * will error immediately as well, and all other Observables will be unsubscribed.
+ *
+ * `combineLatest` accepts as optional parameter `project` function, which takes
+ * as arguments all values that would normally be emitted by resulting Observable.
+ * `project` can return any kind of value, which will be then emitted by Observable
+ * instead of default array. Note that `project` does not take as argument that array
+ * of values, but values themselves. That means default `project` can be imagined
+ * as function that takes all its arguments and puts them into an array.
+ *
+ *
+ * @example <caption>Combine two timer Observables</caption>
+ * const firstTimer = Rx.Observable.timer(0, 1000); // emit 0, 1, 2... after every second, starting from now
+ * const secondTimer = Rx.Observable.timer(500, 1000); // emit 0, 1, 2... after every second, starting 0,5s from now
+ * const combinedTimers = Rx.Observable.combineLatest(firstTimer, secondTimer);
+ * combinedTimers.subscribe(value => console.log(value));
+ * // Logs
+ * // [0, 0] after 0.5s
+ * // [1, 0] after 1s
+ * // [1, 1] after 1.5s
+ * // [2, 1] after 2s
+ *
+ *
+ * @example <caption>Combine an array of Observables</caption>
+ * const observables = [1, 5, 10].map(
+ *   n => Rx.Observable.of(n).delay(n * 1000).startWith(0) // emit 0 and then emit n after n seconds

- * If a comparator function is not provided, an equality check is used by default.
- * As the internal HashSet of this operator grows larger and larger, care should be taken in the domain of inputs this operator may see.
- * An optional parameter is also provided such that an Observable can be provided to queue the internal HashSet to flush the values it holds.

+ * If a keySelector function is provided, then it will project each value from the source observable into a new value that it will

+ * In JavaScript runtimes that support `Set`, this operator will use a `Set` to improve performance of the distinct value checking.
+ *
+ * In other runtimes, this operator will use a minimal implementation of `Set` that relies on an `Array` and `indexOf` under the
