this on Objects

Lesson

58.3`this` is Not Bound

The object that the this keyword refers to does not depend on where the method is defined. It only depends on the object that invokes the function it is used in.

In the example below, this is used inside a function definition. The function is then assigned to two different objects.

In the example above:

When admin.displayGreeting() is invoked, this refers to admin.
When user.displayGreeting() is invoked, the value of this is user.
When guest.greeting.displayGreeting() is invoked, the value of this is guest.greeting.
