30秒学会 JavaScript 片段 – renameKeys

Replaces the names of multiple object keys with the values provided.

Use Object.keys() in combination with Array.prototype.reduce() and the spread operator (...) to get the object’s keys and rename them according to keysMap.

代码片段

const renameKeys = (keysMap, obj) =>
  Object.keys(obj).reduce(
    (acc, key) => ({
      ...acc,
      ...{ [keysMap[key] || key]: obj[key] }
    }),
    {}
  );

使用样例

const obj = { name: 'Bobo', job: 'Front-End Master', shoeSize: 100 };
renameKeys({ name: 'firstName', job: 'passion' }, obj); // { firstName: 'Bobo', passion: 'Front-End Master', shoeSize: 100 }
