    Google maps api v3 doesn’t need a key like v2. You are encouraged to use v3 because of the support for devices like iphone and android.

    Googe maps api v3 has been implemented using modified MVC framework. .

    Any state changes of an MVC object (such as a map) for example, are
    handled through setters and getters of a particular format. As well,
    all state of the MVC objects are stored as properties of that object,
    and all observation of state changes through event handlers is of a
    particular format as well.
