Angular 2 Event emitters vs Subject
angular
Solution
There is not much difference. `EventEmitter` extends `Subject`.
The Angular2 team stressed the fact though, that `EventEmitter` should not be used for anything else then `@Output()`s in components and directives.
The Angular team has stated that they may change the underlying implementation of `EventEmitter` and break user code that uses `EventEmitter` for something it wasn't intended for. That's the main difference.
Problem
In Angular 2 what is the difference between Event Emitter and Subject for announcing an event? It seems like event emitters are less complicated to declare....Which way is preferred by Angular 2? ``` dataRefreshEvent = new EventEmitter(); private companyDataAnnouncedSource = new Subject(); companyDataAnnouncedSource$ = this.companyDataAnnouncedSource.asObservable(); ```
