如何循环多维数组以获取值

let multiDimensionalArray = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

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

function traverseArray(array) {
  for (let i = 0; i < array.length; i++) {
    if (Array.isArray(array[i])) {
      traverseArray(array[i]); // 如果元素是数组，则递归调用
    } else {
      console.log(array[i]); // 如果元素不是数组，则打印值
    }
  }
}

let multiDimensionalArray = [
  [1, 2, [3, 4]],
  [5, [6, [7, 8]], 9]
];

traverseArray(multiDimensionalArray);

let multiDimensionalArray = [
  [1, 2, [3, 4]],
  [5, [6, [7, 8]], 9]
];

let flatArray = multiDimensionalArray.flat(Infinity); // Infinity 表示无限深度

flatArray.forEach(value => console.log(value));
