How does that compare to writing tests and checking code coverage?

The docs says that it tries to explore all the branches of the AST, isn't that what coverage is doing?

I might be missing something.

JS Studio does it for you. Best to think of it along the lines of a fuzzer for JS.

In addition of having your friends and colleagues being a reference, we want to also give you hard data about the libraries you are (considering) using like issue tracker stats, stack overflow answer rates, mailing list activity ... This is just a glimpse of what we want to build. We have a vision that we want to build with our users. As a result, the product will certainly be different from what initially intended.

We are beta testing with some customers right now. We plan on rolling out progressively as we improve the product and make our first users happy. Sign up to be kept int the loop !

It is not live yet for everyone, we are testing it as we are building it with a subset of users.

The demo is available at the end of this page http://linkurio.us/product/

For Linkurious.js there are some examples over here https://github.com/Linkurious/linkurious.js

All infos on the toolkit are available on http://linkurio.us/toolkit/
