As someone who's become a React core contributor since React was released a year ago and had the opportunity to work with a handful of people from the Facebook frontend team, I want to say that I'm really impressed with the quality of the JavaScript libraries that Facebook has released. React is the obvious big one, but other smaller projects like regenerator and jstransform are awesome too. I'm excited to see Jest join the party. Congrats guys. :)
