React Native’s base set of components are amazing! <View> enforcing flexbox and defaulting to {flexDirection: 'column', position: 'relative'}? So smart.

ref is one of two special props in React — the other being key — because it isn't really a prop. Instead of being passed in to the associated component as a this.props.ref, React snatches it up and uses it to associate a reference to the component's instance or DOM node.

An “Immutable Component” is a component that, after rendering once, can not re-render (i.e. it has shouldComponentUpdate() { return false }).

React.cloneElement() allows us to clone a runtime element (not the class), and apply an enhancement to it.
