Chapter 1: Getting Started with Reactive Streams

1. What are the principles of the Reactive Manifesto?

The Reactive Manifesto defines the following principles:

• Message-Driven: All application components should be loosely coupled and communicate using messages
• Responsive: An application must respond to user input in a timely manner
• Resilient: An application must isolate failures to individual components
• Scalable: An application must react to changes in workload

2. What are Reactive Extensions?

Reactive Extensions are libraries in imperative languages that enables us to write asynchronous, event-driven reactive applications. The libraries enable us to express asynchronous events as a set of observables. This enables us to build application components that can receive and process these async events. On the other hand, there are also event producers, which push these events.
