  5. * Creates an output Observable which concurrently emits all values from every
  6. * given input Observable.

  8. * <span class="informal">Flattens multiple Observables together by blending
  9. * their values into one Observable.</span>

  12. *
  13. * `merge` subscribes to each given input Observable (either the source or an
  14. * Observable given as argument), and simply forwards (without doing any
  15. * transformation) all the values from all the input Observables to the output
  16. * Observable. The output Observable only completes once all input Observables
  17. * have completed. Any error delivered by an input Observable will be immediately
  18. * emitted on the output Observable.
  19. *
  20. * @example <caption>Merge together two Observables: 1s interval and clicks</caption>
  21. * var clicks = Rx.Observable.fromEvent(document, 'click');
  22. * var timer = Rx.Observable.interval(1000);
  23. * var clicksOrTimer = clicks.merge(timer);
  24. * clicksOrTimer.subscribe(x => console.log(x));
  25. *
  26. * @example <caption>Merge together 3 Observables, but only 2 run concurrently</caption>
  27. * var timer1 = Rx.Observable.interval(1000).take(10);
  28. * var timer2 = Rx.Observable.interval(2000).take(6);
  29. * var timer3 = Rx.Observable.interval(500).take(10);
  30. * var concurrent = 2; // the argument
  31. * var merged = timer1.merge(timer2, timer3, concurrent);
  32. * merged.subscribe(x => console.log(x));
