The issue here is that for some reason I often struggle to remember which function sorts in ascending order [(b-a) or (a-b)].

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]
