Script Preparation code:

        .filter((key) => key in obj)
        .reduce((res, key) => ({
            ...res,

};
for (var i = 0; i <= 100000; i++) {

}

Tests:

Lodash
arr.map(function (element) { return _.pick( element, 'type', 'subtype', 'card_last4', 'card_type', 'card_exp_month', 'card_exp_year', 'card_country', 'something' ); });
Native
arr.map(function (element) { const { type, subtype, card_last4, card_type, card_exp_month, card_exp_year, card_country, something } = element; return { type, subtype, card_last4, card_type, card_exp_month, card_exp_year, card_country, something }; });
Manual pick with property names
const props = [ "type", "subtype", "card_last4", "card_type", "card_exp_month", "card_exp_year", "card_country", "something" ]; arr.map(function (element) { const res = {}; for(let prop of props){ res[prop] = element[prop] } return res; });
Manual pick
arr.map(function (element) { return { type: element.type, subtype: element.subtype, card_last4: element.card_last4, card_type: element.card_type, card_exp_month: element.card_exp_month, card_exp_year: element.card_exp_year, card_country: element.card_country, something: element.something }; });
Filter
const props = [ "type", "subtype", "card_last4", "card_type", "card_exp_month", "card_exp_year", "card_country", "something" ]; arr.map(function (element) { return pick(element,props) });
