The best way to load external JavaScript Posted at July 28, 2009 09:00 am by Nicholas C. Zakas Tags: Blocking, JavaScript, Performance Not too long ago, I wrote about loading JavaScript without blocking by creating a dynamic <script> tag. When <script> tags are in the flow of an HTML document, the browser must stop rendering and wait for the script file to download and execute before continuing (example).

Why You Haven't Learned How to Code Yet Over the past year there’s been unprecedented enthusiasm for learning to code. From NY Mayor Mike Bloomberg’s pledge to the White House’s national summer effort, programming has never been such a valuable career move and somehow it has even managed become a bit trendy, too (depending on your geographical location). With all this new energy comes initiatives like Code Year, which lets anyone pledge to learn to code with weekly tutorials via Codecademy. So maybe you signed up, or perhaps you did some research on your own, but here we are and you still can’t code… If this situation applies to you, know that you’re not alone. Learning any language is hard to do, and programming requires countless hours of practice before you can really start making something impressive.

DOM DocumentFragments I was playing around with DOM DocumentFragments recently, in JavaScript, seeing what I could make with them. Roughly speaking, a DocumentFragment is a lightweight container that can hold DOM nodes. It’s part of the DOM 1 specification and is supported in all modern browsers (it was added to Internet Explorer in version 6). In reading up on them I came across an interesting point, from the specification: Furthermore, various operations — such as inserting nodes as children of another Node — may take DocumentFragment objects as arguments; this results in all the child nodes of the DocumentFragment being moved to the child list of this node. This means that if you take a bunch of DOM nodes and append them to a fragment then you can simply append the fragment to the document, instead (and achieve the same result – as if you had appended each node individually).
How To Start Being A Web Developer (Quickly) Big questions that’s often asked on a variety of forums. “What can I do to become a developer?” The question has puzzled many and often yields a list of books (that no one other than the poster has/will read), list of websites (that are WAY too advanced), and a battle over languages and definitions.

Green Felt News » How we hash our Javascript for better caching One of the problems we use to see frequently on Green Felt happened when we’d update a Javascript API: We’d add some parameters to some library function and then update some other files so that they called the function with the new parameters. But when we’d push the changes to the site we’d end up with few users that somehow had the old version of one of the files stuck in their cache. Now their browser is causing old code to call new code or new code to call old code and the site doesn’t work for them. We’d then have to explain how to reset their cache (and of course every browser has different instructions) and hope that if they didn’t write back that everything went OK.
Triggering CSS3 Transitions With JavaScript At the beginning of this month I wrote a post accompanied by five demo pages that showed that CSS3 transitions could be triggered with a number of different events/states in CSS. That alone should help you see how these types of simple animations work. But let’s take this a bit further. CSS pseudo-classes and media queries (which I used in that other post to trigger the transitions) represent certain states for certain elements.
