Question regarding StateNode

[lmuntaner]

Hi!

I found this very helpful. I am still not sure I fully understand everything, but I think it helped me get a better deep understanding of React.

However, I have a question which I am not sure whether it's a typo.

In the list of properties of a Fiber you say:

stateNode: The local state associated with this fiber

However, then it seems that the stateNode actually contains an instance of a component.

For example, in processChildContext:

parameters(fiber, type, parentContext)
	const instance = fiber.stateNode;
  	const childContextTypes = type.childContextTypes;
	let childContext
	get the instance of the child context using the stop/start PhaseTimers
	return {...parentContext, ...childContext};

When you are talk about the local state of the Fiber, what do you mean? Is that the local state of the component?

Thanks and keep sharing this notes!
