In fact, your example suffers from the same problem: It sorts in descending order (20,10,2,1) instead of ascending (1,2,10,20).
Telling JS to use a TypedArray [Int8,...,BigInt64] instead can solve this without remembering and providing your own comparator:
Float64Array.from([1,2,10,20]).sort(); //[1,2,10,20]
