JavaScript中锯齿多维数组的元素级算术运算

// 创建一个锯齿多维数组
var jaggedArray = [[1, 2, 3], [4, 5], [6, 7, 8, 9]];

// 定义一个函数，实现元素级算术运算
function arithmeticOperation(array, operator, operand) {
  for (var i = 0; i < array.length; i++) {
    for (var j = 0; j < array[i].length; j++) {
      // 根据运算符进行相应的算术运算
      if (operator === '+') {
        array[i][j] += operand;
      } else if (operator === '-') {
        array[i][j] -= operand;
      } else if (operator === '*') {
        array[i][j] *= operand;
      } else if (operator === '/') {
        array[i][j] /= operand;
      }
    }
  }
  return array;
}

// 调用函数进行元素级算术运算
var result = arithmeticOperation(jaggedArray, '+', 1);
console.log(result);
