Or, to be more accurate, they're polyfillable in ES5 + setTimeout().
The latter can't currently be expressed in pure ES, as we haven't yet
added the concept of the event loop to the ES spec (it's planned for
ES7, I believe), but that's irrelevant for our purposes, as the event
loop *does* exist in de facto ES in every browser, and non-browser ES
environments like Node.
