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.

Creating Custom Shipping Methods In Magento

In this tutorial, we will use Magento’s powerful shipping-method code abstraction to create a shipping carrier. We will create two shipping methods that provide a fixed shipping price, allow for free shipping promotions, define logic based on an item’s weight and, finally, make it all configurable in the admin panel.

This tutorial assumes that you are familiar with how to create a Magento module. If you are not, please first refer to an earlier tutorial in this series, “The Basics of Creating a Magento Module.” To begin, you will need a Community or Enterprise installation of Magento, either locally or on a server that you are able to access.

Speed Up Your Mobile Website With Varnish

Imagine that you have just written a post on your blog, tweeted about it and watched it get retweeted by some popular Twitter users, sending hundreds of people to your blog at once. Your excitement at seeing so many visitors talk about your post turns to dismay as they start to tweet that your website is down — a database connection error is shown.

Speed Up Your Mobile Website With Varnish

Or perhaps you have been working hard to generate interest in your startup. One day, out of the blue, a celebrity tweets about how much they love your product. The person’s followers all seem to click at once, and many of them find that the domain isn’t responding, or when they try to sign up for the trial, the page times out.

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.

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.

An Introduction To DOM Events

Click, touch, load, drag, change, input, error, resize — the list of possible DOM events is lengthy. Events can be triggered on any part of a document, whether by a user’s interaction or by the browser. They don’t just start and end in one place; they flow though the document, on a life cycle of their own. This life cycle is what makes DOM events so extensible and useful. As developers, we should understand how DOM events work, so that we can harness their potential and build engaging experiences.

An Introduction To DOM Events

Throughout my time as a front-end developer, I felt that I was never given a straight explanation of how DOM events work. My aim here is to give you a clear overview of the subject, to get you up to speed more quickly than I did.
