-/**
- * Combines multiple Observables to create an Observable whose values are
- * calculated from the latest values of each of its input Observables.
- *
- * <span class="informal">Whenever any input Observable emits a value, it
- * computes a formula using the latest values from all the inputs, then emits
- * the output of that formula.</span>
- *
- * ![](combineLatest.png)
- *
- * `combineLatest` combines the values from all the Observables passed as
- * 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).
- *
- * 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 these values but the last
- * will be lost. On the other hand, if some Observable does not emit a 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.
- *
- * ## Examples
- * ### Combine two timer Observables
- * ```javascript
- * import { combineLatest, timer } from 'rxjs';
- *
- * const firstTimer = timer(0, 1000); // emit 0, 1, 2... after every second, starting from now
- * const secondTimer = timer(500, 1000); // emit 0, 1, 2... after every second, starting 0,5s from now
- * const combinedTimers = 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
- * ```
- *
- * ### Combine an array of Observables
- * ```javascript
- * import { combineLatest, of } from 'rxjs';
- * import { delat, starWith } from 'rxjs/operators';
- *
- * const observables = [1, 5, 10].map(
- *   n => of(n).pipe(
- *     delay(n * 1000),   // emit 0 and then emit n after n seconds
- *     startWith(0),
- *   )
- * );
- * const combined = combineLatest(observables);
- * combined.subscribe(value => console.log(value));
- * // Logs
- * // [0, 0, 0] immediately
- * // [1, 0, 0] after 1s
- * // [1, 5, 0] after 5s
- * // [1, 5, 10] after 10s
- * ```
- *
- *
- * ### Use project function to dynamically calculate the Body-Mass Index
- * ```javascript
- * import { combineLatest, of } from 'rxjs';
- * import { map } from 'rxjs/operators';
- *
- * const weight = of(70, 72, 76, 79, 75);
- * const height = of(1.76, 1.77, 1.78);
- * const bmi = combineLatest(weight, height).pipe(
- *   map(([w, h]) => w / (h * h)),
- * );
- * bmi.subscribe(x => console.log('BMI is ' + x));
- *
- * // With output to console:
- * // BMI is 24.212293388429753
- * // BMI is 23.93948099205209
- * // BMI is 23.671253629592222
- * ```
- *
- * @see {@link combineAll}
- * @see {@link merge}
- * @see {@link withLatestFrom}
- *
- * @param {ObservableInput} observable1 An input Observable to combine with other Observables.
- * @param {ObservableInput} observable2 An input Observable to combine with other Observables.
- * More than one input Observables may be given as arguments
- * or an array of Observables may be given as the first argument.
- * @param {function} [project] An optional function to project the values from
- * the combined latest values into a new value on the output Observable.
- * @param {SchedulerLike} [scheduler=null] The {@link SchedulerLike} to use for subscribing to
- * each input Observable.
- * @return {Observable} An Observable of projected values from the most recent
- * values from each input Observable, or an array of the most recent values from
- * each input Observable.
