  1. GOING REACTIVE
    An Introduction to RxProgramming
    Hamburg, 29. September 2017

    View Slide

  2. Rx.Observable.flatMapLatest(selector, [thisArg])
    Projects each element of an observable sequence into a new
    sequence of observable sequences by incorporating the
    element's index and then transforms an observable sequence
    of observable sequences into an observable sequence
    producing values only from the most recent observable
    sequence.
    WTF?
