Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

The Secret Passions of Git Checkout

The Hand of God

Git checkout can do almost anything ... or, at least, many things. It can switch branches. It can mix and match branches. It can resolve merge conflicts. It can give you a scratchpad to test things.

Basically git checkout does two things:
