Answer 1

You can do something like this. The last route will match everything else that the other routes didn't fulfill. The order of the routes also matters in this case.

routes : {
    '' : 'profile',
    'detailedProfile' : 'detailedProfile',
    'moreReviews' : 'moreReviews',
    '*invalidRoute' : 'profile' /* catch all route */
}
