Mascara is the latest in a “Write code in X and translate it to JavaScript” system to be launched.

Tom Trenka has followed up his last post on String performance with a deep dive on IE that dispells the myth of Array.join. Tom goes through tons of tests across versions of IE and using varying sizes of data. In Conclusion First things first—with the performance improvements with IE7, we no longer need to consider Read the rest…

John Resig pointed us to Johnson, a project that “wraps JavaScript in a loving Ruby embrace.” It seems to give you a JavaScript interpreter that you can pass a context into to. The simple examples are: < View plain text > ruby require "johnson" Johnson.evaluate("4 + 4") # => 8 Johnson.evaluate("4 + foo", :foo Read the rest…

As I say in this podcast interview, I got an early look at 280 Slides the application that launched yesterday to much acclaim. People are calling it “Keynote on the Web”, which the team finds very humbling, and hope that one day they have all of the great features (and more!). As you can hear Read the rest…

Bob Matsuoka has written a guest article on the topic of lazy script loading. Thanks so much Bob! A recent article “Lazily load functionality via Unobtrusive Scripts” discussed how to lazily load Javascript script files by appending script elements to the HEAD tag. While this works as expected, I’ve found that for best results, you Read the rest…

I saw two articles that were both looking at similar issues. Firstly, Pete Higgins has looked at the fact that Google Analytics is normally loaded via serial script tags which cause the rest of the application to wait and created a simple wrapper that changes things. We have all seen the tell tale: “waiting for Read the rest…

Watching people discuss SquirrelFish has been a real pleasure. The WebKit team set the tone with their initial technical detail. Instead of a post saying “We have a fast JSVM now. woohoo!”, they told us why it is faster, and what they can work on from here. The community is continuing the conversation. David Mandelin Read the rest…

Steven Levithan has been flagrant by creating a simple way to remove nested patterns with a while loop and a replace: < View plain text > javascript var str = "abc<1<2<>3>4>def"; while (str != (str = str.replace(/< [^<>]*>/g, ""))); // str -> "abcdef" Notice that the regex in this one-liner doesn’t try to Read the rest…

Aza Raskin wrote about SocialHistory.js, a small library he wrote that detects which social networks that you use, and using that data to show the user only those sites as areas to work with. E.g. if you use Digg, show “digg this” etc. He uses the technique that Jeremiah Grossman and Robert Hansen came up Read the rest…

I just got to announce the Google AJAX Libraries API which exists to make Ajax applications that use popular frameworks such as Prototype, Script.aculo.us, jQuery, Dojo, and MooTools faster and easier for developers.

Jeff Watkins is updating his MVC library, Coherent, and is wondering if he should add declarative syntax for child widgets. Currently, you have to write a lot of init() setup code, but instead he would like to do something like: < View plain text > javascript sample.MyWidget= Class.create(coherent.Widget, { init: function() Read the rest…
