Let’s use this topic as a good resource to post good React-related tutorials!
great docs from Dan Abramov’s awesome React drag-and-drop module. Unique in that it provides side-by-side comparisons of ES5, ES6 and ES7 syntax
This one is really good - minimal boilerplate, discusses good wireframing habits - and as a bonus, it touches on Redux! Edit - it also covers some really useful ES6 tricks. Highly recommend it!
