Wes Bos released a series of videos on React.js.

Together, we will build “Catch of the Day” — a real-time app for a trendy seafood market where price and quantity available are variable and can change at a moments notice. We will build a menu, an order form, and an inventory management area where authorized users can immediately update product details.
Wes has released some really learning resources on, amongst others the terminalsublime. A while ago he also appeared on Full Stack Radio.  I'm pretty sure his new batch of videos will be top notch!
