jsLex 为网站开发人员提供一套工具包来优化网站，利用这个工具可以在下面两个方面对网站进行优化：
Web Site Optimization - Instead of ant files and command lines, jsLex gives developers wizards that they can access via Eclipse and Aptana making tasks such as; JavaScript and CSS concatenation, creation of sprites and compression of JavaScript and CSS as simple as right clicking on a file.
JavaScript Profiling Tools - provides developers with a complete picture of the performance issues with-in their Ajax application. By auto injecting profiling markers with jsLex's ant task or Eclipse wizards, don't need to modify their code to track down bottlenecks, minimizing coding errors.
