ion. Thi…consumers. Update this file to export all items that should be available to your library consumers. Currently, this entry point is named index.ts- however, the current Angular Package Format v6 suggests the name should be public_api.ts by convention. This file's name may be updated by the Nrwl.Nx team to align with the APF suggested name.
Marcin Grzywaczewski: Observables are actually a little lower level than a promise, believe it or not. Observables can be sync or async, they can be unicast or multicast, and they’re zero to N values. Promises are always async, always multicast, and always one value. Also promises are immediately invoked where observables are lazy. One could build a promise from an observable, but not the other way around.
