如何在javascript中创建循环中的多维数组/对象

let multiArray = [];
for (let i = 0; i < 3; i++) {
    multiArray[i] = [];
    for (let j = 0; j < 3; j++) {
        multiArray[i][j] = i * j;
    }
}
console.log(multiArray);

[
  [0, 0, 0],
  [0, 1, 2],
  [0, 2, 4]
]

let multiObject = {};
for (let i = 0; i < 3; i++) {
    multiObject[i] = {};
    for (let j = 0; j < 3; j++) {
        multiObject[i][j] = { value: i * j };
    }
}
console.log(multiObject);

{
  0: { 0: { value: 0 }, 1: { value: 0 }, 2: { value: 0 } },
  1: { 0: { value: 0 }, 1: { value: 1 }, 2: { value: 2 } },
  2: { 0: { value: 0 }, 1: { value: 2 }, 2: { value: 4 } }
}
