This evaluates to NaN for some reason:

'10' % 0

Since JS doesn't really differentiate strings from numbers, except on the places it does, it makes sense to make sure you are working with numbers.

also, that suprises me a lot, you'd think this is one of the places where it treats stuff as numbers
