The mantra around the monastery is always "don't trust Javascript." That is true if a server-side check is omitted altogether, but Javascript can provide a very fast preliminary client-side check that doesn't require the long trip to the server. The JS validation protects the user with a fast check, while the server side protects the internals.

I think both can work in tandem, with the understanding that the server-side validation will always be there.
