waitOn and Multiple subscriptions in iron-router

Hi, this time i want to share how to do multiple subscription in iron-router. as we know iron-router has waitOn as great feature, we can wait subscription finsih before rendering template or page. this is how to the simple way to use waitOn :

this.route('posts', {
 path: '/posts',
 template: 'tmp_posts',
 waitOn: function () {
 return Meteor.subscribe('posts');
 },
 onBeforeAction: function () {
 },
 onAfterAction: function () {

 },
 data: {

 }
});

and this is how to subscribe more than one subscription

this.route('posts', {
 path: '/posts',
 template: 'tmp_posts',
 waitOn: function () {
 return [Meteor.subscribe('posts'),Meteor.subscribe('users')];
 },
 onBeforeAction: function () {
 },
 onAfterAction: function () {

 },
 data: {

 }
});

Hope this help you.
