javascript多维数组(Int8Array)示例

// 创建一个2x3的Int8Array多维数组
const multiDimArray = new Int8Array(2 * 3);

// 将一维数组转换为多维数组
const rows = 2;
const cols = 3;
const multiDim = [];
for (let i = 0; i < rows; i++) {
  multiDim[i] = [];
  for (let j = 0; j < cols; j++) {
    const index = i * cols + j;
    multiDim[i][j] = multiDimArray[index];
  }
}

// 设置和获取多维数组的值
multiDim[0][0] = 10;
multiDim[0][1] = 20;
multiDim[0][2] = 30;
multiDim[1][0] = 40;
multiDim[1][1] = 50;
multiDim[1][2] = 60;

console.log(multiDim[0][0]); // 输出: 10
console.log(multiDim[1][2]); // 输出: 60
