This is an extension to an old version of chrome + a custom istanbul reporter. This combo gives you the power to view what JS gets evaluated on any website.
First we have to download an old version of chrome from here.
The reason why we have to use an old version is because we are utilizing a cool API chrome used to have to preprocess any JS file before it gets evaluated by v8. This feature was reverted here.
Next go to chrome://extensions and enable developer mode. From there click on load unpacked extension and load the extension folder here.
