删除对象数组中的特定元素

function deleteElement(arr, target) {
  for (let i = arr.length - 1; i >= 0; i--) {
    if (arr[i] === target) {
      arr.splice(i, 1);
    }
  }
  return arr;
}

// 示例用法
const myArray = [
  { id: 1, name: "John" },
  { id: 2, name: "Jane" },
  { id: 3, name: "Tom" },
  { id: 4, name: "Jane" }
];

const newArray = deleteElement(myArray, { id: 2, name: "Jane" });
console.log(newArray);
