wait, I might have misunderstood your problem ... so you want to stop
iterating, right ?
When that is the case, you can simply drop the iteration like this:
myArray.slice().filter(function (value, index, original) {
// do your stuff
if (conditionSatisfied) {
original.length = 0;
}
});
there, you can break the iteration as easy as that :-)
