How to change the local state of a component using the parent method?

React

There are two components: parent => child (childs are displayed in the map)
There is a method for changing state in parent, I pass it to child.

5. Here you need to call the parent method on click - https://dropmefiles.com/H4aY6
UPD: solved the problem, one instance of the object was created, further only links to it. Therefore, state changed in all elements of MAPA.

Answer 1

If you need to change the local state in child, use setState, if you need to get data in child from parent - pass it through props.
