Methods of an object are just properties whose values are functions. Let's add a .greet() method to our person object:

var person = {
firstName : 'Boaz',
lastName : 'Sender',
greet : function(name) {
log( 'Hi, ' + name );

person.greet( person.firstName );
The .greet() method in the example above received a string, name, as its argument. When we called the method, though, we simply passed in the value of the firstName property of the person object. If we wanted a super-flexible .greet() method that could greet anyone, this might be what we want. But it probably makes more sense that the .greet() method will greet the particular person.

The meaning of this

Inside of a method — indeed, inside of any function — there is a special keyword available to us: this. It refers to the object that is the context in which the function was called.

When we call person.greet(), the context object is person itself. This means that we can use this to access a property of the person object from directly within the .greet() method.
