Benchmark: Comparing various JavaScript sorting methods (large workload)

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

function shuffle(array) {
    var i = array.length,
        j = 0,
        temp;
    while (i--) {
        j = Math.floor(Math.random() * (i + 1));
        temp = array[i];
        array[i] = array[j];
        array[j] = temp;
    }
    return array;
}

var words = ["aaa", "bbb", "ccc", "AAA", "BBB", "CCC", "123", "234", "345", "aaa", "bbb", "ccc", "AAA", "BBB", "CCC", "123", "234", "345", "aaa", "bbb", "ccc", "AAA", "BBB", "CCC", "123", "234", "345", "aaa", "bbb", "ccc", "AAA", "BBB", "CCC", "123", "234", "345", "가나다", "나다라", "마바사"];
var words1 = [];
var n = [];

// Repeat the words array enough times to exceed 10,000 words
while (words.length < 10000) {
    words.push(...words);
}

for (i = 0; i < words.length; i++) n.push(i);
var ranNums = shuffle(n);
for (i = 0; i < words.length; i++) words1.push(words[ranNums[i]]);
console.log('ORIGINAL', words1);

Tests:

localeCompare base
words1.sort((a,b) => a.localeCompare(b));
localeCompare sensitive
words1.sort((a,b) => a.localeCompare(b, undefined, { sensitivity: 'accent' }));
Intl.Collator base
const collator = new Intl.Collator('en', { numeric: true, sensitivity: 'base' }); words1.sort((a, b) => collator.compare(a, b));
Intl.Collator sensitive
const collator = new Intl.Collator('en', { numeric: true, sensitivity: 'accent' }); words1.sort((a, b) => collator.compare(a, b));
sort comparator with casing
words1.sort((a,b) => { if (a.toLowerCase() < b.toLowerCase()) { return -1; } if (a.toLowerCase() > b.toLowerCase()) { return 1; } return 0; });
sort comparator with custom heuristic
words1.sort(function (a, b) { return (a < b ? -1 : (a > b ? 1 : 0)); });
sort comparator
words1.sort();
