JavaScript Code Optimization and Minimization Tools

The title speaks for itself: here is an interesting slideshow analyzing what makes JavaScript slow and offering solutions.

Common Errors To Know And Compability Issues

Top 10 Things that JavaScript Got Wrong

JavaScript, if only by default, is one of the most popular programming languages available. Over the years, it’s been labeled as a nightmare to work with, and, to some extent, this is true! However, more often than not, what people mean to say is that the DOM API is a nightmare. Nevertheless, there are a handful of flat-out errors in the language.

Javascript – Event compatibility tables

Quick overview of events browser compatibility, assuming that you know the three event registration models (traditional, W3C and Microsoft) as well as event bubbling and capturing. Most of the time is spent on the cross-browser events; the links in the first compatibility table lead to even more compatibility tables with detailed information about these events. Basic browser support for the Microsoft and W3C events is merely tested, without delving too deeply into the details.

How to Plan for the Absence of JavaScript

Though the methods used to gather website traffic statistics call into question the validity of the stats themselves, the fact is that some of your website’s visitors will have JavaScript disabled. You could divide your traffic sources into four broad categories: Search engines, mobile visitors, visitors using screen readers and visitors who have JavaScript turned off. When planning your information architecture and design, you must figure out how to deal with these special groups. Here is assembled a few recent real-world scenarios to find clarity on the issue.
