JSC is a powerful debugging tool for your websites javascript. It allows you to view bugs aswell as execute javascript commands right into your developing website. JSC Isnt fully visible when your page loads, a small box will follow your scroll position, you can open up the JSC console by clicking this box. Once open you can view errors or execute javascript right into your page. And whats better is that just a few lines of code are needed to include the console into your page!! Have you ever been irritated by Internet Exploreres pathetic debugging utility for javascript? i know i have, so why not include this into your website whilst your developing it? WARNING!! because JSC allows the execution of javascript into your website, we recommend you DO NOT use JSC on publicly accessible websites! JSC is also free!!
