What's New In A Spec
HTML5 DOM4 ES5 ES 2015 ES 2016 ES 2017 XHR2 SVG2 We list all new stuff that comes with more recent specifications, relative to the previous version (whatever "version" means nowadays). I will happily receive any request for changes if something is not up-to-date or is inaccurate. Please raise an issue on Github. Ideally, I'd love you to give me proof that what you say is true.

When milliseconds are not enough - performance.now | Blog | Chrome for Developers
Date.now() // 1337376068250 performance.now() // 20303.427000007 You'll notice the two above values are many orders of magnitude different. performance.now() is a measurement of floating point milliseconds since that particular page started to load (the performance.timing.[navigationStart](https://www.w3.org/TR/navigation-timing/#dom-performancetiming-navigationstart) timeStamp to be specific).

Prototype JavaScript framework: Prototype 1.7.1
Not long ago, I tagged Prototype 1.7.1, an update 18 months in the making. It features an overhaul of our DOM library and better coexistence with ES5 methods, but quite a bit more as well. I’m sure you’re curious about why it’s taken so long. But first let’s look at what’s been done in 1.7.1. When last we spoke, I told you about the plans we had for 1.7.0.1 and 1.7.1 — a bugfix release and a minor

DOMQL
Lately its getting more and more obvious that web development is indeed a basic human right. And it should be accessible to every developer in the industry. jQuery played its part by making web development easier for designers, CoffeeScript for Rubyists and Pythonistas, Dart for Java devs, ClojureScript for Lispers etc. But what about DBAs? aren't they equally human? Should they be doomed to suffe
Laconic DOM Library
Laconic offers an intuitive approach to generating DOM content in JavaScript. The source code is available on GitHub. Consider the code necessary to produce a simple table hierarchy with the standard DOM API: var firstTh = document.createElement('th'); firstTh.appendChild(document.createTextNode('first name')); var secondTh = document.createElement('th'); secondTh.appendChild(document.createTextNo
Big boost to DOM performance - WebKit's innerHTML is 240% faster | Blog | Chrome for Developers
We're very happy to see that some common DOM operations have just skyrocketed in speed. The changes were at the WebKit level, boosting performance for both Safari (JavaScriptCore) and Chrome (V8). Chrome Engineer Kentaro Hara made seven code optimizations within WebKit; below are the results, which show just how much faster JavaScript DOM access has become: DOM performance boosts summary div.inner

Sorry; your browser does not support svg! http://www.meetup.com/framsia/ < 100ms "0.1 second [100ms] is about the limit for having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result."

History of Mozilla’s DOM bindings
The Mozilla project has gone through a number of different JS bindings for the DOM in Mozilla. This post is basically a trip down memory lane, walking through how JS running in the SpiderMonkey JavaScript engine in Mozilla has communicated with the C++ DOM throughout the years. But before I get into that, let’s clarify what DOM bindings are. DOM bindings are the pieces of code that sit in between

How to adjust an iframe element’s height to fit its content | 456 Berea Street
In an ideal world there would always be a clean way of displaying data supplied by a third party on your site. Two examples would be getting the data in JSON or XML format from a Web Service and having an API to code against. But you don’t always have any of those options. Sometimes the only way of incorporating data from a third party is by loading it in an iframe element. A few examples are fina
