I’ve been doing a lot of work, lately, with JavaScript inheritance – namely for my work-in-progress JavaScript book – and in doing so have examined a number of different JavaScript classical-inheritance-simulating techniques.

getBoundingClientRect is a method, first introduced by Internet Explorer 5 (and now included in Firefox 3), which provides the top, right, bottom, and left offset coordinates of an element.

Mozilla developer ‘Pavlov’ wrote up some extensive details on memory use in Firefox 3. I highly recommend that you check it out. I borrowed some of his data and created another view of the results. For example, here’s the results from Windows Vista of a number of browsers: Note that both Safari 3 and IE […]

Today, at SXSW, I hosted a panel discussion on the “Secrets of JavaScript Libraries.” We set out to discuss the behind-the-scenes nitty-gritty code that powers the universal features of the most popular JavaScript libraries. I think the presentation went quite well. I think we could’ve, easily, done a 2 hour talk with all the content […]

Everyone from users, to web developers, to extension developers were in attendance. We ran a mini contest, giving away some prizes for the best, original, Firefox extension […]
