       *   x % 2 === 1 ? Rx.Observable.of('a', 'b', 'c') : Rx.Observable.empty()

       * result.subscribe(x => console.log(x));

       * // Results in the following to the console:
       * // x is equal to the count on the interval eg(0,1,2,3,...)
       * // x will occur every 1000ms
       * // if x % 2 is equal to 1 print abc
       * // if x % 2 is not equal to 1 nothing will be output
