I have method that makes one subscribe and brings me an object array huge.
getItems() {
this.service.getItems()
.subscribe(items => { this.listaItems = items;},
() => console.log('msg de erro')
I need to assign the return to a global variable, called listaItems right when I open my page.
so I did:
ngOnInit(){
this.getItems();
console.log(this.listaItems) // undefined
}
Yet it has returned undefined instead of my result.
He looks like "jump" me this.getItems(); and run my console.log(this.listaItems) first.
service:
getItems =() => this.httpService.get(`apiURl`);
Yes, it will return Undefined, pq is logging the variable, but it has not yet been filled in with the value returned by the service. If you involve the variable in a setTimeout will see that the variable needs a time to get the return!

It makes sense, since my return is great. In this case, how to expect it to be filled out and then log?

Dude you won’t be able to do anything with the variable before it has a value, and it only gets a value in the method getItems(), then you’ll have to do what you need to do there.
