But I can't find details of the event loop consensus. Is there any consensus about event loop abstraction in ES6?
Only that a suitable hook is needed that embedders can implement. Luckily that's simple WRT existing semantics (we are oblivious to future turns at the language level) and doesn't demand that we import the event loop itself into the language. The only requirement is that promises are async WRT the calling code. Delivery at the end of the current turn is allowed. Object.observe will require that we define an order, but until then, hand waving is sufficient. > Thanks, > Yusuke Suzuki > > _______________________________________________ > es-discuss mailing list > [email protected] > https://mail.mozilla.org/listinfo/es-discuss >
