To collect data from multiple children, or to have two child components communicate with each other, you need to declare the shared state in their parent component instead. The parent component can pass the state back down to the children by using props; this keeps the child components in sync with each other and with the parent component.

This is why Square currently ignores the value prop passed to it by the Board. We will now use the prop passing mechanism again. We will modify the Board to instruct each individual Square about its current value 'X', 'O', or null.
