What is Reactive Programming?
Reactive Programming
Representing and responding to Changes in Data Over Time
Observables
AKA
Streams
When you typically think of data...
you may think of one of these
when you think of data "in RP"
it's more like this
TIME X Data
=
Observable
key to streams is ...
Some Examples of Observables\ Streams
Subscribers
How we Listen to observables
Push vs Pull
Iteration vs Subscription
Functional Reactive Programming
-
RFP is a MODEL of implementing RP
- The "HOW" of Reactive Programming
- Leverages FP to compose responses to change in streams
Event subscription example
Benefits of Rp
- Unified Concurrency\Threading\Asynchronicity Model
- Abstracting Event\Database\HTTP\MSG\ETC Handling
- Baked in Error Handing
- (Arguably) Simpler code
Benefits of Functional Rp
- Uses existing functional programming concepts to compose responses to change in streams
- (Arguably) Even simpler code
imho
my personal anecdotal accounts and opinions
to be taken with a grain of salt
