About This Class

Welcome to Part 8 of the course.

In this section we'll discuss services and observables.

Services Explained - Services are used to encapsulate logic that can be re-used across multiple components.

Constructor - The constructor is a special method that is executed when a new instance of the class is being created.

Observables Explained - Observables are part of the reactive extensions library also known as RxJS and are used extensively in Angular 2.

HTTP in Angular 2 - We use http in order to send and receive data. Angular makes it easy for us to send these requests.
