// how could you rewrite the following to make it shorter?
if (foo) {
    bar.doSomething(el);
} else {
    bar.doSomethingElse(el);
}

// how could this code be rewritten in order to remove the if?
if (foo) {
    bar.doSomething();
}

// given the following code,  and  assuming that each created object has a
// 'destroy' method, how would you  destroy all of the objects contained in  the
// myObjects object?

    gizmo : new myApp.Gizmo(),
    widget : new myApp.Widget()
