残念なことに。

+)他者コード

moves.forEach(n => {
       const idx = board.findIndex(r => r[n-1] > 0);
        if(idx === -1) {
            return;
        }
  ...

findIndexサンプルコード

const array1 = [5, 12, 8, 130, 44];

const isLargeNumber = (element) => element > 13;

console.log(array1.findIndex(isLargeNumber));

完全なコード

function solution(board, moves) {
    var answer = 0;
    var temp = [];
    moves.forEach(n => {
       const idx = board.findIndex(r => r[n-1] > 0);
        if(idx === -1) {
            return;
        }
        const target = board[idx][n-1];
        const prev = temp.length > 0 ? temp[temp.length-1] : undefined;
        if(target === prev){
            answer += 2;
            temp.pop();
        }else {
            temp.push(target);
        }
        board[idx][n-1] = 0;
    });
    return answer;
}
