Benchmark: Lodash Pick vs Native destructuring vs Manual Picks vs pick fn

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.11/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
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" ]; function pick(element, props) { const res = {}; for(let prop of props){ res[prop] = element[prop] } return res; } arr.map((element) => pick(element, props));
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 }; });
compiled pick function
const props = [ "type", "subtype", "card_last4", "card_type", "card_exp_month", "card_exp_year", "card_country", "something" ]; function pickBuilder(props) { const obj = props.map((prop) => `if (has.call(el, '${prop}')) res.${prop} = el.${prop}`).join(';'); return new Function('el', `const has = Object.prototype.hasOwnProperty; const res = {}; ${obj}; return res;`); } const pick = pickBuilder(props) arr.map((element) => pick(element));
