I got "undefined" after adding the map operator
Angular version: 7
Map import:
import { map } from 'rxjs/operators';
With Map:
this.restaurantService.getRestaurants().pipe(map((restaurant:any) => restaurant.name)).subscribe((restaurants) => {
console.log(restaurants); // undefined
});
Not necessary "name" field is returning undefined at any field
Without Map
this.restaurantService.getRestaurants().subscribe((restaurants) => {
console.log(restaurants); // [{...,name: 'lorem'},{...},...]
});
Service:
getRestaurants(): Observable<_Restaurant[]> {
return this.get(api.restaurants) as Observable<_Restaurant[]>;
};
I logged the restaurant inside the map operator and I got an array which is should be object
.pipe(map(restaurant => {
console.log(restaurant); //[{},{}] !!
return restaurant.name;
}))
Any Idea why I'm getting the undefined?
this.restaurantService
.getRestaurants()
.pipe(map((restaurants:any[]) => restaurants.map(restaurant => restaurant.name)));
