How do I use share some state data in one React component function with another? Both are children of yet another component. (I am a React newbie so perhaps somewhat naively I tried: 1) defined an exported const from my ap.jsx with a structure whose properties were the state. Seems like when queried the structure was returning null. 2) cannot use props as that's one way one from parent to child).

I suppose the best answer is: it depends.
However, the most simple solution would be to hold the value in a parent component and pass it down to both child components through props.
If you want to skip few nesting levels, you could reach for React context or state management tools like redux but that is already a heavy tool. Hard to say what exactly is best in your case with context you shared so far.

If you want to share state, you can use Context concept or Redux which is a library for sharing library.
Here is some useful link for you.
