I'm a self taught programmer and I got my hands on a TicTacToe project, but I got stucked at the following part. I did a relatively working TicTacToe(inspired from youtube) then I wanted to do a responsive TicTacToe matrix that changes it's numbers from(0-9) in X's and O's in the console depending of the inputs of the first game. But now I'm stuck at trying to find a way to check the winners of the matrix oh and I'm trying to start the "checking" from the last X or O
Hopefully seeing the code is much more easier to understand. I'd really really appreciate some help!

</html>I think you can simplify your isPlayerWinner function by ignoring if you are looking for Xs or Os. You must assume the last token used was not the winner in the previous turn or the game would already be finished.
So if you have matrix = [[0,1,2],[3,4,5],[6,7,8]] and the numbers will be progressively replaced by x or o just check if all items in a combination are equal
function isPlayerWinner(){
for(let i=0; i<3; i++){
const row = matrix[i][0] === matrix[i][1] && matrix[i][1] === matrix[i][2];
const column = matrix[0][i] === matrix[1][i] && matrix[1][i] === matrix[2][i];
if(column || row){
return true
}
}
if(matrix[0][0] === matrix[1][1] && matrix[1][1] === matrix[2][2]){
return true;
}
if(matrix[0][2] === matrix[1][1] && matrix[1][1] === matrix[2][0]){
return true;
}
return false
}
