크레인 인형뽑기 게임 [Javascript]

내가 작성한 코드

function solution(board, moves) {
    const box = []
    const temp = []
    let counter = 0
    transpose(board)
    const x = board.map((elm)=> elm.filter(x => x > 0))
    moves.forEach((elm,idx) => {
        if (x[elm-1].length !==0){
           box.push(x[elm-1][0])
           x[elm-1].shift() 
        }
    })
    temp.push(box[0])
    box.map((elm,idx)=>{
        if (idx > 0) {
            if( +temp.slice(-1).join("") === elm){
                counter+=2
                temp.pop()
            }else{
                temp.push(elm)
            }
        }
    })
    return counter
}
function transpose(matrix) {
  for (let i = 0; i < matrix.length; i++) {
    for (let j = 0; j < i; j++) {
      [matrix[i][j], matrix[j][i]] = [matrix[j][i], matrix[i][j]];
    }
  }
