为每个键添加前缀:

const obj = {foo: 'bar'}

const altObj = Object.fromEntries(
  Object.entries(obj).map(([key, value]) => 
    // Modify key here
    [`x-${key}`, value]
  )
)

// altObj = {'x-foo': 'bar'}

还有一种最强大的REDUCE方法。

数据= {\ key1:“value1”，key2:“value2”，key3:“value3”}; 键文件夹= {\ key1:“firstkey”，key2:“secondkey”，key3:“thirdkey” mappedData = Object.keys . .还原((obj,k) =>对象。assign(obj， {\ [keyMap]]:数据[k]}，{\}; 控制台日志(mappedData); 第一个“value1”、“secondkey”、“value2”、“thirdkey”、“value3”……

const clone = (obj) => Object.assign({}, obj);

const renameKey = (object, key, newKey) => {

    const clonedObj = clone(object);
  
    const targetKey = clonedObj[key];
  
  
  
    delete clonedObj[key];
  
    clonedObj[newKey] = targetKey;
  
    return clonedObj;
     };

  let contact = {radiant: 11, dire: 22};





contact = renameKey(contact, 'radiant', 'aplha');

contact = renameKey(contact, 'dire', 'omega');



console.log(contact); // { aplha: 11, omega: 22 };

我会这样做:

function renameKeys(dict, keyMap) {
  return _.reduce(dict, function(newDict, val, oldKey) {
    var newKey = keyMap[oldKey] || oldKey
    newDict[newKey] = val 
    return newDict
  }, {})
}

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 });

一般来说，如果你想获得一个新的对象(不改变原来的对象)，根据keyMap重命名键-你可以使用以下基于lodash mapKeys的实现:

const {mapKeys} = require('lodash');
const renameKeys = (obj, keyMap) => _.mapKeys(obj, (value, key) => keyMap[key] || key);

使用的例子:

renameKeys({a: 1, b: 2, c: 3}, {c: 'p', a: 'm'})
> {m: 1, b: 2, p: 3}
