If you do much work with Backbone.js inevitably you are going to have to end up debugging some silly mistake you have made, I know I have been making about 5000 a second over the past few days.
Luckily I read today that there is a Google Chrome extension out that can help debug Backbone.js issues. The code can be found here along with an easy to follow installation guide.
One thing the guide does not mention is that you will more than likely need to restart Chrome to get this to work, I know I did.
Whilst it is clearly still in early development, I have already been putting it to use and getting good stuff back from it
