将具有某些属性的对象移到数组前面

function moveObjectsWithPropertyToFront(arr, property) {
  let newArr = [];
  let index = 0;

  for (let i = 0; i < arr.length; i++) {
    if (arr[i].hasOwnProperty(property)) {
      newArr.push(arr[i]);
      arr.splice(i, 1);
      i--;
    }
  }

  for (let i = newArr.length - 1; i >= 0; i--) {
    arr.unshift(newArr[i]);
  }

  return arr;
}

// 示例用法
let objects = [
  { name: "John", age: 25 },
  { name: "Jane", age: 30 },
  { name: "Bob", age: 35 },
  { name: "Alice", age: 40 },
];

let updatedArray = moveObjectsWithPropertyToFront(objects, "age");
console.log(updatedArray);
