como usar o renameKeys no javascript es6

January 04, 2020

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 }
