Question 1 of 10

From my EmployeeManagement system I need to get employees data from two different web services which returns Employee data from two different database.

webservice1 : https://employee-management-system.com/departments/it/employees

webservice2 : https://employee-management-system.com/departments/admin/employees

What is the possible way to achieve this parallelly?

Both a & b

getEmployees() : Observable<any[]> {.

let response1 = this.http.get(webservice1);.

let response2 = this.http.get(webservice2);.

return forkJoin([response1,response2]);.

getEmployees() {

let employees = [];

this.http.get(webservice1).subscribe((res1)=> {

employees.push(res1);

this.http.get(webservice2).subscribe((res2)=> {

employees.push(res2);

}, (err)=> {});

}, (error) => {});

return employees;

}

None of the above
