Object Oriented JavaScript with Getters and Setters for Properties. This is but just one example that seems rather friendly and straight forward. #OOP

OOP-GetterAndSetter-Demo.js

var Person = new function () {
	var _firstName = null;
	var _lastName = null;

	// Public Properties
	this.FirstName = {
		get: function () {
			return _firstName;
		},
		set: function (value) {
			_firstName = value;
		}
	};

	this.LastName = {
		get: function () {
			return _lastName;
		},
		set: function (value) {
			_lastName = value;
		}
	};
};

// Set First and Last Name Properties
Person.FirstName.set('John');
Person.LastName.set('Doe');

// Display Full Name
alert(Person.FirstName.get() + " " + Person.LastName.get());
