删除一个值并重新构造一个二维数组

function deleteAndReconstructArray(arr, valueToDelete) {
  let newArray = [];

  for (let i = 0; i < arr.length; i++) {
    let row = arr[i];
    let newRow = [];

    for (let j = 0; j < row.length; j++) {
      if (row[j] !== valueToDelete) {
        newRow.push(row[j]);
      }
    }

    newArray.push(newRow);
  }

  return newArray;
}

// 示例用法
let originalArray = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];
let valueToDelete = 5;

let resultArray = deleteAndReconstructArray(originalArray, valueToDelete);
console.log(resultArray);
