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

// pseudocode

other private instance variables;
that = a new object
Add privileged methods to that
return that;
}
