You can debug javascript within chrome alone.
See this
How do you launch the JavaScript debugger in Google Chrome?

visual studio only debugs js running in IE, as far as I'm aware. chrome has a console-type debugger which I have no idea how to use- it's available from the page icon>developer>javascript console. you could also look into chrome extensions to see if anyone has created a nicer debugger. i know there's a firebug extension available but i'm not sure what features it offers.
if all else fails:
alert('made it this far!');
