如何在NodeJs中修改数组内的JSON key名称

const fs = require('fs');

const data = [
  { id: 1, name: 'John', age: 25 },
  { id: 2, name: 'Jane', age: 30 },
  { id: 3, name: 'Bob', age: 35 }
];

function modifyArrayKey(keyToModify, dataArray) {
  for (let i = 0; i < dataArray.length; i++) {
    const modifiedData = {};
    for (let key in dataArray[i]) {
      if (key === keyToModify) {
        modifiedData['newKey'] = dataArray[i][key];
      } else {
        modifiedData[key] = dataArray[i][key];
      }
    }
    dataArray[i] = modifiedData;
  }
}

modifyArrayKey('id', data);

const modifiedDataString = JSON.stringify(data, null, 2);

fs.writeFile('modifiedData.json', modifiedDataString, (err) => {
  if (err) throw err;
  console.log('修改后的数据已写入到modifiedData.json文件');
});
