Introducing Live Extensions For Better-DOM: What They Are And How They Work

After recently writing an article on “Writing A Better JavaScript Library For The DOM”, I realized that the topic is indeed a very complex one and that it's important to understand what exactly live extensions are and how they work.

Introducing Live Extensions For Better-DOM: What They Are And How They Work

In today's article, I will answer most questions that were asked regarding "live extensions" and help you get going with this new concept.

Understanding JavaScript’s Function.prototype.bind

Function binding is probably your least concern when beginning with JavaScript, but when you realize that you need a solution to the problem of how to keep the context of this within another function, then you might not realize that what you actually need is Function.prototype.bind().

render: function () {

    this.getAsyncData(function () {

        this.specialFunction();

        this.anotherSpecialFunction();

    }.bind(this));

}

The first time you hit upon the problem, you might be inclined to set this to a variable that you can reference when you change context. Many people opt for self, _this or sometimes context as a variable name. They’re all usable and nothing is wrong with doing that, but there is a better, dedicated way.

Writing A Better JavaScript Library For The DOM

At present, jQuery is the de facto library for working with the document object model (DOM). It can be used with popular client-side MV* frameworks (such as Backbone), and it has a ton of plugins and a very large community.

Writing A Better JavaScript Library For The DOM

As developers’ interest in JavaScript increases by the minute, a lot of people are becoming curious about how native APIs really work and about when we can just use them instead of including an extra library. Lately, I have started to see more and more problems with jQuery, at least my use of it.

An Introduction To Full-Stack JavaScript

Nowadays, with any Web app you build, you have dozens of architectural decisions to make. And you want to make the right ones: You want to use technologies that allow for rapid development, constant iteration, maximal efficiency, speed, robustness and more.

An Introduction To Full-Stack JavaScript

You want to be lean and you want to be agile. You want to use technologies that will help you succeed in the short and long term. And those technologies are not always easy to pick out. In my experience, full-stack JavaScript hits all the marks.

Reinventing The Tech Conference Experience

If you had to name one thing that could have been better at the last conference or meetup you attended, what would it be? I bet you’d say that the content or the interaction could have been better in some way. I created Onslyde to solve this problem. It’s a free service and open-source project that (hopefully) will make public speaking easier and conferences better.

Reinventing The Tech Conference Experience

The motivation for the project came from my own speaking engagements in the tech industry. I wanted to see how many people in the audience actually agreed or disagreed with what I was saying. I also wanted to leverage their experience and knowledge to create a better learning environment.

The Future Of Video In Web Design

Federico was the only other kid on the block with a dedicated ISDN line, so I gave him a call. It had taken six hours of interminable waiting (peppered with frantic bouts of cursing), but I had just watched 60 choppy seconds of the original Macintosh TV commercial in Firefox, and I had to tell someone. It blew my mind.

The Future Of Video In Web Design

Video on the Web has improved quite a bit since that first jittery low-res commercial I watched on my Quadra 605 back in 7th grade. But for the most part, videos are still separate from the Web, cordoned off by iframes and Flash and bottled up in little windows in the center of the page. They’re a missed opportunity for Web designers everywhere.

Laying The Groundwork For Extensibility

The Web has succeeded at interoperability and scale in a way that no other technology has before or since. Still, the Web remains far from “state of the art”, and it is being increasingly threatened by walled gardens. The Web platform often lags competitors in delivering new system and device capabilities to developers.

Laying The Groundwork For Extensibility

Worse, it often hobbles new capabilities behind either high- or low-level APIs, forcing painful choices (and workarounds) on developers. Despite browser versions being released much faster, new capabilities still take a long time to materialize, and often do so in forms that are at best frustrating and at worst nearly useless to large swathes of the developer community for solving real-world needs.
