With the proliferation of content management systems we’re seeing an increase in the use of JavaScript. WordPress, Movable Type, Joomla, Drupal all employ JavaScript to add enhanced functionality to their sites. Plugins abound promising Web 2.0 features, higher interactivity, and increased user engagement. The problem with this trend is that JavaScript usage is inceasing at an alarming clip (see Figure 1). The HTTArchive shows the average page uses 14 external JavaScript and 190K of code.
