This differs depending on which browser you're writing for. On my version of Firefox, this is the most efficient:

var array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
var length = array.length;
for (length -= 2; length > -1; length -= 1)
{
array.push(array[length]);
array.splice(length, 1);
}

This is according to http://jsperf.com/js-array-reverse-vs-while-loop/5
