javascript 创建复杂的多维数组

Posted 2021-05-03

let nestedArray = [ // top, or first level - the outer most array
  ['deep'], // an array within an array, 2 levels of depth
  [
    ['deeper'], ['deeper'] // 2 arrays nested 3 levels deep
  ],
  [
    [
      ['deepest'], ['deepest'] // 2 arrays nested 4 levels deep
    ],
    [
      [
        ['deepest-est?'] // an array nested 5 levels deep
      ]
    ]
  ]
];


console.log(nestedArray[2][1][0][0][0]);
// logs: deepest-est?


nestedArray[2][1][0][0][0] = 'deeper still';
console.log(nestedArray[2][1][0][0][0]);
// now logs: deeper still
