Didn’t belive it. tried it. died a little more inside.

From MDN:

If compareFn is not supplied, all non-undefined array elements are sorted by converting them to strings and comparing strings in UTF-16 code units order.

So, if you’re trying to sort numbers, [6, -2, 2, -7].sort((a, b) => a - b)

Its converting numbers to strings.

Imagine going for a JavaScript coding interview and failing because of this 😂

Blessed are those that use Array.sort without passing it arguments
