array vs optional (v3)

Revision 3 of this benchmark created on

Setup

arrTest = [];
optionalTest = [];
arrResult = 0;
optionalResult = 0;

for (let i = 0; i < 9999; i++) {
	const arrobj = {
		num: i % 3,
		opt: []
	};
	const optobj = {
		num: i % 3,
	};
	const r = Math.random();
	if (i % 2 === 0) {
		const fn = (arg) => {
		    return r + arg;	
		};
		arrobj.opt.push(fn);
		optobj.opt = fn;
	}
	arrTest.push(arrobj);
	optionalTest.push(optobj);
}

Teardown

console.log(arrResult, optionalResult);
