 Create an object named calculator with methods add, subtract, and multily#
 Imlement the calculate method in the calculator object, which takes an oeration ('add', 'subtract', or
'multily') and two numbers#
 Use call to erform an addition oeration using the calculate method#
 Use aly to erform a multilication oeration using the calculate method with arguments as an array#
 Create another object named discountCalculator with a discount ercentage roerty and a method
alyDiscount#
 Use bind to create a new function calculateDiscount that is bound to the discountCalculator object and
can be reused.    */
