Reactive Programming: Hot Vs. Cold Observables
The Observer Pattern is at the core of reactive programming, and observables come in two flavors: hot and cold. This is not explicit when you are coding, so this article explains how to tell the difference and switch to a hot observable. The focus is on hot observables. The concepts here are relevant to all languages that support reactive programming, but the examples are in C#. It’s critical to understand the distinction before you start doing reactive programming because it will bring you unstuck if you don’t. Reactive Programming It’s hard to clearly define what Reactive Programming is because it spans so many languages and platforms, and it has overlap with programming constructs like events in C#. I recommend reading through the Wikipedia article because it attempts to give a history of reactive programming and provide objective information. In a nutshell, reactive...
