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();
