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.
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 }
