Usage of prototype
prototype it is a property of Function, and it is used to add some extra function to an existing function, or override the function.
If you create an empty function.
var funvar=function () {
//Empty Function
}
You can add any function from outside of that function by prototype keyword, like below
funvar.prototype.firstName = "Merbin";
funvar.prototype.lastName = "Joe";
funvar.prototype.SDate = new Date();
funvar.prototype.fullName = function () {
alert(this.firstName + " " + this.lastName);
};
Now we can call that function as usually by creating objects.
var ObjVar = new funvar();
ObjVar.fullName(); // Merbin Joe
alert(ObjVar.SDate); // true
