Keep going:

    return (cellA > cellB) * 1 + (cellA < cellB) * -1;

More:

    return Math.sign(cellA - cellB);

[XCSme]

You don't need the * 1 multiplication:

   return (cellA > cellB) - (cellA < cellB);

does work for NaN... rookie mistake, eh

Math.sign trick doesn't work for strings.

[XCSme]

That's true, but the default string comparison sometimes isn't that useful, right? I somehow assumed the data is numbers only, rookie mistake :)

    'ana' > 'Bob'
    '2' > '123'

You usually want to clearly define the order or pre-process the strings in some way (trim them, same casing, etc).

[amelius]

Well, you can pass the strings through .toUpperCase() before comparing them.
