This is true. > JavaScript does not have an event loop (as I mentioned elsewhere) so > [Futures are entirely expressible] is not true. The only part of futures that isn't expressible today in ES5 (I believe) is the requirement that callbacks be called in the next tick when .then() is called on a resolved promise. > Lifting that up to > JavaScript seems difficult. Fortunately, this isn't true, because the module loader system requires us to add the event loop to ES6.
