Benchmark: lookup vs closure declaration

Tests:

create closure
let num = Math.random(); let elem = { click: (elem) => num * 2 };
create object lookup
function reusable_click_handler(elem) { return elem.num * 2; } let num = Math.random(); let elem = { num, click: reusable_click_handler };
click closure
let num = Math.random(); let elem = { click: (elem) => num * 2 }; elem.click(elem);
click object lookup
function reusable_click_handler(elem) { return elem.num * 2; } let num = Math.random(); let elem = { num, click: reusable_click_handler }; elem.click(elem)
