attach functions to objects | Chinese Rule of Eight

First declare your objects

Person1 = {

name: "gary",

age: 25

};

Person2 = {

name: "ricky",

age: 35

};

Then you declare a function…

displayName = function() {

console.log("name is: " + this.name + ", age is: " + this.age);

}

You can literally attach functions to objects like so:

//attach function definition for test, that is attribute of myapp

Person1.showName = displayName;

Person2.whatsMyName = displayName;

Where the function uses ‘this’ to access the calling object’s attributes.
Using them like this:

1 2	Person1.showName(); Person2.whatsMyName();

would give:

name is: gary, age is: 25
name is: ricky, age is: 35
