Benchmark: JavaScript .sort() vs .toSorted ()vs [...].sort()

Script Preparation code:

array = Array.from({
    length: 50
}, (x, i) => (Math.round(Math.random() * (i + .01) * 1000)))

sortNumeric = (a, b) => (Number(a) - Number(b));

Tests:

Array.sort()
array.sort(sortNumeric);
Array.toSorted()
array.toSorted(sortNumeric)
[...Array].sort()
[...array].sort(sortNumeric);
