Tutorial Code Allows Overwrite of Squares

Tic-Tac-Toe Rule Violation

The code in the tutorial allows for overwriting played squares.

Solution

Once the handleClick function has retrieved squares from state, immediately return if the particular square is already truthy.

I have a fix in my fork, but cannot create the PR to main. Is there a different branch I should branch from to start?

Closing, since we're no longer updating the legacy docs.
