Four Games, React, Tailwind, framer-motion, recoil

This was the most challenging project so far. I had problems with creating proper logic for checking who is the winner. The hardest was with diagonal checking. I've created 3 separate functions for this,

checkRows();
checkColumns();
checkDiagonals();

each of them is creating a new corresponding array, and this array is used with

checkWinner([arrayToCheck]);

to check if the actual row, column, or diagonal is the winner.
