Hi all, I'm writing to ask some clarifications about the sample code published in the "Routing and navigation" on the angular.io website.
Full URL is: https://angular.io/docs/ts/latest/guide/router.html Here is the code where I need your idea: ngOnInit() { this.route.params // (+) converts string 'id' to a number .switchMap((params: Params) => this.service.getHero(+params['id'])) .subscribe((hero: Hero) => this.hero = hero); } Since I'm a novice on TypeScript this is quite confusing for me; the code above should get the passed parameters through a navigation link and the parameter read by an observable. The questions: - How I have to remanage the code to get just the parameter and put it on a property? - I cannot realize what the switchMap and subscribe method are exactly; can someone explain me or point me to a documentation about? Note that I already took a look at http://reactivex.io Thank you very much for help!
