Lodash pick

arr.map(function (element) {
	return _.pick(
      	element,
      	'type',
        'subtype',
        'card_last4',

});

 
arr.map(function (element) {    return _.pick(        element,        'type',        'subtype',        'card_last4',        'card_type',        'card_exp_month',        'card_exp_year',        'card_country',        'something'    );});

Native pick

function pick(object, keys) {
  return keys.reduce((obj, key) => {
     if (object && object.hasOwnProperty(key)) {
        obj[key] = object[key];
     }
     return obj;
   }, {});
}

arr.map(function (element) {
    return pick(
      element,
      ['type',
      'subtype',
      'card_last4',
      'card_type',
      'card_exp_month',
      'card_exp_year',
      'card_country',
