Functional (1 of 2)

Create a function which has 4 stepso It creates new object

- Object literal

- Constructor function with new keyword

- Object.create()

- call a function which returns an object

o It has private (local) instance variables and methodso It augments that new objecto return that new object

other private instance variables;

that = a new object

Add privileged methods to that

return that;

}
