I want to convert Observable to User[].

After googling, I found a solution BUT, the conversion is done only inside map.

    users : User[] = [];

    this.userService.getUsersList() // Observable<Any>
          .map((listUsers: Array<any>) => {
           let result:Array<User> = [];
            if (listUsers) {
              listUsers.forEach((erg) => {
                result.push(new User(erg.id, erg.name, erg.username, erg.email, erg.password, erg.age, erg.active, erg.roles));
              });
            }
            console.log('----------------Size: ' + result.length);  // Output: 5 --> TRUE
            return result;
          })
          .subscribe(users => this.users = users);



     console.log('----------------Size: ' + result.length);        // Output: 0 --> FALSE

So it's Ok, I can get the size of the array User[] inside map. My problem is, how can I get the size or read the array User[] outside map.

Thanks in advance.
