Tests:

Lodash omit
const user = { name: 'Banana', phone: '1032012301d0s', address: 'Rua Banana'} const userWithoutPhone = _.omit(user, ["phone"]);
Object assign and delete
const user = { name: 'Banana', phone: '1032012301d0s', address: 'Rua Banana'} const userWithoutPhone = Object.assign({}, user); delete userWithoutPhone["phone"];
Babel transpile
const user = { name: 'Banana', phone: '1032012301d0s', address: 'Rua Banana'} // babel output function _objectWithoutProperties(obj, keys) { var target = {}; for (var i in obj) { if (keys.indexOf(i) >= 0) continue; if (!Object.prototype.hasOwnProperty.call(obj, i)) continue; target[i] = obj[i]; } return target; } const userWithoutPhone = _objectWithoutProperties(user, ["phone"]);
Modified transpile using reduce
const user = { name: 'Banana', phone: '1032012301d0s', address: 'Rua Banana'} function objectWithoutKeys(obj, keys) { return Object.keys(obj).reduce((newObject, key) => { if (keys.indexOf(key) === -1) newObject[key] = obj[key]; return newObject; }, {}); } const userWithoutPhone = objectWithoutKeys(user, ["phone"]);
Native using destructure
const user = { name: 'Banana', phone: '1032012301d0s', address: 'Rua Banana'} const { address, ...userWithoutPhone } = user
