Why I Don't Use Classes
Recently, one of my teammates noted that our projectâ€™s codebase doesnâ€™t have a lot of classes. The observation wasnâ€™t framed positively or negatively. It was just an observation about a particular code style of the team as a whole. I didnâ€™t think much about it at the time. But looking back, this observation has lead to some good self-reflection on what I value when writing software. I didnâ€™t write

How to make setTimeout and setInterval work with large timeout values
I just ran into a probl em with setTimeout and setInterval.

I was writing an application that needed a 30+ day delay and my setTimeout callbacks were firing instantly. Here's code that demonstrates it: setTimeout(function () { alert("doesn't work - insta

A Javascript stacktrace in any browser
This is now a mature project on GitHub! Please submit comments/issues there. Chances are that if youâ€™ve done any significant Javascript work, youâ€™ve run into a situation where part of the debugging process could be much improved if you just had the function call stack. Iâ€™m going to give you some ways of doing this with and without the popular Firebug extension and have some examples of their uses.
