my favorite router so far

simple-router.js

define([
    // Application.
    'app',
    'modules/section'
], function (app, Section) {

    var Router = Backbone.Router.extend({
        routes      : {
            ''          : 'index',
            '*route'    : 'allRoutes'
        },
        initialize  : function () { app.useLayout(); },
        // Whatever you want the 'index' to be.
        index       : function () { Section.change('facts'); },
        // Routes assume a corresponding template with the same name.
        // rarr because we like jurassic park.
        allRoutes   : function (route) {
            var rarr = route.split('/');
            if (rarr.length > 1) {
                Section.change(rarr[0], rarr[1]);
            } else {
                Section.change(rarr[0]);
            }
        }
    });

    return Router;

});
