如何在Java Script中打印以下多维数组？

const multiArray = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

for (let i = 0; i< multiArray.length; i++) {
  let row = '';
  for (let j = 0; j< multiArray[i].length; j++) {
    row += multiArray[i][j] + ' ';
  }
  console.log(row);
}

1 2 3
4 5 6
7 8 9

const threeDimArray = [
  [
    [1, 2],
    [3, 4]
  ],
  [
    [5, 6],
    [7, 8]
  ]
];

function printThreeDimArray(array) {
  for (let i = 0; i< array.length; i++) {
    for (let j = 0; j< array[i].length; j++) {
      let row = '';
      for (let k = 0; k< array[i][j].length; k++) {
        row += array[i][j][k] + ' ';
      }
      console.log(row);
    }
    console.log('---');
  }
}

printThreeDimArray(threeDimArray);
