Replaces the names of multiple object keys with the values provided.
- Use
Object.keys()
in combination withArray.prototype.reduce()
and the spread operator (...
) to get the object’s keys and rename them according tokeysMap
.
代码实现
const renameKeys = (keysMap, obj) =>
Object.keys(obj).reduce(
(acc, key) => ({
...acc,
...{ [keysMap[key] || key]: obj[key] }
}),
{}
);
const obj = { name: 'Bobo', job: 'Front-End Master', shoeSize: 100 };
renameKeys({ name: 'firstName', job: 'passion' }, obj);
// { firstName: 'Bobo', passion: 'Front-End Master', shoeSize: 100 }
