Angular2 Observables, Http, and separating services and components

What Angular1 brought, Angular2 takes away – for a good reason. No more Promises in ng2! See how observables make Angular2 a reactive, functional platform. We’ll roll up our sleeves and get something practical done with Angular2’s Http service, and we’ll get some data via the new Http service – it's quite a bit different than the Angular 1 $http service semantically, but serves the same purpose, but is also more fully featured.
