It's slightly more complex than [my undersatnding of] your original
phrasing, but in a word, yes, it behaves essentially as in Python.
e.g., using Task.js [1], with a proper (and trivial) definition of
wait(), the following implements a polling loop that does not block the
event loop:
Tasks.spawn(function* () {
while (true) {
yield wait();
poll();
}
});
