[EDIT: I've added a part 2 to this blog post, to address some of the feedback that has come up: https://gist.github.com/getify/706e5e10822a298375da40f9cc1fa295]
Recently, this article on "The JavaScript Block Statement" came out, and it received some good discussion in a reddit thread. But the general reaction seems to be against this approach. That saddens me.

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

| This disables app transport security and allows non-HTTPS requests. | |
| Note: it is not recommended to use non-HTTPS requests for sensitive data. A better | |
| approach is to fix the non-secure resources. However, this patch will work in a pinch. | |
| To apply the fix in your Ionic/Cordova app, edit the file located here: | |
| platforms/ios/MyApp/MyApp-Info.plist | |
| And add this XML right before the end of the file inside of the last </dict> entry: |
The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:
Generally one implements notifications by listening for events on specific models but if one wishes to have a single global message interchange, it could be done as follows:
var pubsub = new Backbone.Model;
View1 = Backbone.View.extend({
initialize: function(){
pubsub.bind('custom event', callback);
}
