Benchmark: luxon-v-Intl-v-datefns format, luxon-v-Date-v-datefns native parse

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/luxon@2.0.2/build/global/luxon.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.29.0/date_fns.min.js"></script>

Script Preparation code:

window.__dateISO__ = '2021-09-24T07:36:51+0000'
window.__date__ = new Date(__dateISO__);
window.__expected__ = '09/24/2021';
window.__intlFormatter = new Intl.DateTimeFormat('en', {
  year: '2-digit',
  month: '2-digit',
  day: '2-digit',
});

Tests:

moment/luxon - format
var actual = luxon.DateTime.fromJSDate(__date__).toLocaleString(); console.assert(actual === __expected__);
Intl - format
var actual = window.__intlFormatter.format(__date__); console.assert(actual === __expected__);
moment/luxon - parse
var actual = luxon.DateTime.fromISO(__dateISO__).toJSDate(); console.assert(__date__.getTime() === actual.getTime());
Native parse
var actual = new Date(__dateISO__); console.assert(__date__.getTime() === actual.getTime());
date-fns (old) format
var actual = dateFns.format(__date__); console.assert(actual === __expected__);
date-fns (old) parse
var actual = dateFns.parse(__dateISO__); console.assert(__date__.getTime() === actual.getTime());
