JSL (JavaScript Loader)

Do you want an ultra fast web site? Get JSL and optimize your JavaScript loading now!
Imagine there's a 4-lane highway between your web browser and the internet itself. This highway is optimize to let pictures, text, and css fly by. But, when it comes to external scripts, the highway creates a toll booth that slows traffic. The worst part is that pictures text, and css caught behind these scripts have to wait until they pass through. JSL is the latest in toll both avoidance. It creates an express lane that lets all pictures, text, css, and external scripts pass by without worrying about toll booths. That means you save time and money on traffic costs :)
