A demo learned from freeCodeCamp.
User story:
I can play a game of Tic Tac Toe with the computer.
My game will reset as soon as it's over so I can play again.
I can choose whether I want to play as X or O.
P.S So rookie I am, some logic in this project is too hard to understand for me, I need to do it by myself later when I do some further study about JavaScript.
