Javascript objects and Classes

1. Create a person object with four members:
VaR person = new object (); person. firstname = "bill"; person. lastname = "Gates"; person. Age = 56; person. eyecolor = "blue ";
 

2. Create a person object. The object has four members, which is similar to the previous one.

VaR person = {firstname: "John", lastname: "doe", Age: 50, eyecolor: "blue "};

3. Create a person class with member variables and member functions, which can be instantiated.

Function OB (a, B) {// class construction function, two parameters
This. A =;
This. B = B;
This. Fun = function (x, y) {// member function of the class
Return X + Y;
}
}

// This is a class call:

Var y = new ob (4, 23); // instantiate class ob

VaR P = Y. A; // P = 4
VaR x = Y. Fun (3, 2); // y = 5
