HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>

Script Preparation code:

var arr = [];
var object = { 
	type: 'aaa',
    subtype: 'bbb',
    card_last4:'bbb',
    card_type:'bbb',
    card_exp_month:'bbb',
    card_exp_year:'bbb',
    card_country:'bbb',
    foo: 'bar'
};
for (var i = 0; i <= 100000; i++) { arr.push(object); }

Tests:

lodash pick
arr.map(el => _.pick(el, ['type', 'subtype', 'card_last4', 'card_type', 'card_exp_month', 'card_exp_year', 'card_country']));
native based on reduce
function pick(object, keys) { return keys.reduce((obj, key) => { if (object && object.hasOwnProperty(key)) { obj[key] = object[key]; } return obj; }, {}); } arr.map(el => pick(el, ['type', 'subtype', 'card_last4', 'card_type', 'card_exp_month', 'card_exp_year', 'card_country']));
