Angular Loves Data
summary
Shows how Angular uses RxJS observables, the async pipe and onPush change detection to render immutable data efficiently and demonstrates a working real-time chat app wired to Firebase via angularfire2/angularfire where pushes appear instantly in two tabs. Explains lazy loading to avoid the ~400 KB Firebase SDK until needed, how Apollo GraphQL batches component queries into one request, and how ngrx implements a Redux style immutable store with time travel for debugging.
