This is almost certainly not what you intend. [`_.every`][1] “returns true if all of the values in the list pass the iterator truth test”, which means that it short-circuits as soon as a logical false value is returned. From memory jQuery allows short-circuiting, also, but the return value must be false in this case (whereas any logical false value is sufficient for `_.every`.
