const url = 'http://dummy.restapiexample.com/api/v1/employees'; 
const fetchUsers = async () => {
    try {
       const res = await fetch(url);
     // check for 404 error
       if (!res.ok) { 
           throw new Error(res.status);
       }
       const data = await res.json();
          console.log(data);
       }
       // catch block for network errors
       catch (error) { 
            console.log(error); 
        }
}
fetchUsers( );
