javascript:

    > 1/(-0)
    -Infinity
    > 1/0
    Infinity
    > Object.is(0, -0)
    false

Of course = doesn't actually test equality in javascript. == reports -0 as being equal to +0, but Object.is reports them as different.

See now, I contest this particular defense because it groups together 'javascript' and 'good decision'.
