Jon Bomgardner is a contributor to the jxlib.org project.

It is also a modular library allowing you to pick and choose from the available components as well as giving you the ability to override default behaviors and extend core classes.All of this flexibility is, in large part, du...

Those of you who follow my work over on Clientcide may already be familiar with it, but for the rest of you I wanted to write a blog posts here on MooTools.net about the work I’ve been doing on a library called Behavior - a throwback to the behavior.js library released way back in 2005 which one might consider to be philosophically an ancestor of sorts.PurposeAll well-written web sites / apps that are interactive have the same basic pattern:Each page of a site or app you build is esoteric. It may have any combination of interactive elements, some of which interact with each other (for example, a form validation controller might interact with an ajax controller to prevent it sending ...

This 1.4 release should be fully backward compatible with the 1.3 series.So all changes for 1.4.0:Move Delegation into Core.ECMAScript 5 compatibility fixes.

We at the MooTools headquarters love GitHub for all its features which makes contributing and managing our code much easier than say, five years ago. GitHub is the place to be for all cool JavaScript projects which makes following your projects of interest a lot easier. When we moved to GitHub a long time ago, the ticket system was too basic to be a real solution. Fortunately this has since improved.Especially the additions for milestones and assignees were important for us. With this in place GitHub issues can finally replace Lighthouse.The main advantages are:Everything at one place, one loginEasier to follow MooToolsSimilar to pull requestsA disadvantage is that most of the current iss...
