就我个人而言，重命名对象中的键而不实现额外的沉重插件和轮子的最有效的方法:

var str = JSON.stringify(object);
str = str.replace(/oldKey/g, 'newKey');
str = str.replace(/oldKey2/g, 'newKey2');

object = JSON.parse(str);

如果对象具有无效的结构，还可以将其封装在try-catch中。工作完美无缺:)

function iterate(instance) {
  for (let child of instance.tree_down) iterate(child);

  instance.children = instance.tree_down;
  delete instance.tree_down;
}

iterate(link_hierarchy);

console.log(link_hierarchy);

我想这么做

const originalObj = {
  a: 1,
  b: 2,
  c: 3, // need replace this 'c' key into 'd'
};

const { c, ...rest } = originalObj;

const newObj = { ...rest, d: c };

console.log({ originalObj, newObj });

这是我对pomber函数做的一个小修改; 为了能够获取一个对象数组而不是单独的对象，你也可以激活索引。此外，“键”也可以由数组分配

function renameKeys(arrayObject, newKeys, index = false) {
    let newArray = [];
    arrayObject.forEach((obj,item)=>{
        const keyValues = Object.keys(obj).map((key,i) => {
            return {[newKeys[i] || key]:obj[key]}
        });
        let id = (index) ? {'ID':item} : {}; 
        newArray.push(Object.assign(id, ...keyValues));
    });
    return newArray;
}

test

const obj = [{ a: "1", b: "2" }, { a: "5", b: "4" } ,{ a: "3", b: "0" }];
const newKeys = ["A","C"];
const renamedObj = renameKeys(obj, newKeys);
console.log(renamedObj);

重命名键，但避免改变原始对象参数

oldJson=[{firstName:'s1',lastName:'v1'},
         {firstName:'s2',lastName:'v2'},
         {firstName:'s3',lastName:'v3'}]

newJson = oldJson.map(rec => {
  return {
    'Last Name': rec.lastName,
    'First Name': rec.firstName,  
     }
  })
output: [{Last Name:"v1",First Name:"s1"},
         {Last Name:"v2",First Name:"s2"},
         {Last Name:"v3",First Name:"s3"}]

最好有一个新的数组
