why the output of this code is: 'xyz'?

Question

var Employee = {
company: ’xyz’
}
var emp1 = Object.create(Employee);
delete emp1.company
console.log(emp1.company);

Answer 1

You cannot delete a variable that declared with var
Try
delete Employee.company

Answer 2

emp1 is still an Employee obj and Employee obj has the company value set to 'xyz' if no other value is present.
