In the world of functional reactive programming, a behavior is a value that changes over time. This is exactly what a BehaviorSubject represents: when you subscribe you get the current value, and then you can continue to observe the changes. See http://en.wikipedia.org/wiki/Functional_reactive_programming.
I think a constructive discussion on this topic has been had on the Rx Forums in 2009. Instead of adding adhoc Do operators into your queries, you would add a custom Log/Trace operator. This operator would capture the Subscription, Disposal, OnNext, OnError and OnCompleted events. Depending on your implementation it could just write to the … Read more
No, they are absolutely not the same thing. Reactive Extensions is a library for creating and composing observable streams of data or events (which are actually quite similar). It basically knows nothing about client-server connections or other things. It is focused solely on Observables and is capable of wrapping any collection, stream, event, async method, … Read more
PLINQ (Parallel Linq) is simply a new way to write regular Linq queries so that they run in parallel – in other words, the Framework will automatically take care of running your query across multiple threads so that they finish faster (i.e. using multiple CPU cores). For example, let’s say that you have a bunch … Read more
From: Anton Moiseev’s Book “Angular Development with Typescript, Second Edition.” : Hot and cold observables There are two types of observables: hot and cold. The main difference is that a cold observable creates a data producer for each subscriber, whereas a hot observable creates a data producer first, and each subscriber gets the data from … Read more
