Transcript

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

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?
