Benchmark: Intl.Collator.compare vs localeCompare (numeric)

Script Preparation code:

const minCodePoint = 'a'.charCodeAt(0);
const maxCodePoint = 'z'.charCodeAt(0);
const randomLetter = () => String.fromCharCode(Math.floor(Math.random() * (maxCodePoint - minCodePoint) + minCodePoint));
const createWord = () => Array.from({length: 15}, randomLetter).join('');

var wordsCollator = Array.from({length: 50000}, createWord);
var wordsLocale = [...wordsCollator];
const collator = new Intl.Collator({numeric:true});

Tests:

Intl.Collator
wordsCollator.sort(collator.compare);
localeCompare
wordsLocale.sort((a, b) => a.localeCompare(b, {numeric:true}))
