Updating deep ReactJS state

Question

I have an array of items in a ReactJS component state that I\'m iterating over to create a form. My question is: How do I best update those items when the fields change?

Answer 1

Thought I'd just throw this library out there because it was specifically designed for deeply nested react state,

You can update items within each component and it automatically trickles up without you having to define callbacks to pass the event up.
