在javascript函数中找出一组json数据？

function findJsonData(jsonData, condition) {
  let foundItems = [];

  for (let i = 0; i < jsonData.length; i++) {
    let item = jsonData[i];

    // 在此处根据条件判断选择是否将该项添加到结果数组中
    if (condition(item)) {
      foundItems.push(item);
    }
  }

  return foundItems;
}

let data = [
  { name: "John", age: 25 },
  { name: "Jane", age: 30 },
  { name: "John", age: 35 },
  { name: "Kate", age: 28 }
];

function isNameJohn(item) {
  return item.name === "John";
}

let result = findJsonData(data, isNameJohn);

console.log(result);

[
  { name: "John", age: 25 },
  { name: "John", age: 35 }
]
