function AjaxController(service, data) {
    this.service = service;
    this.data = data;
    // ...
}
 
var JsDic = require('jsdic'); // node, browserify
var dic = new JsDic();
dic
    .value('ajaxUrl', '/some-ajax-action')
    .value('initialData', [1, 2, 3])
    .service('ajaxService', AjaxService)
    .factory('ajaxController', function (ajaxService, initialData) {
        return new AjaxController(ajaxService, initialData);
    });
 
var ctrl = dic.get('ajaxController');
// or
var ctrl = dic.ajaxController;
// or
var ctrl = dic['ajaxController'];
 
// dependencies can be defined explicitly
dic
    .value('ajaxUrl', '/some-ajax-action')
    .value('initialData', [1, 2, 3])
    .service('ajaxService', ['ajaxUrl', AjaxService])
    .factory('ajaxController', ['ajaxService', 'initialData', function (as, id) {
        return new AjaxController(as, id);
