The semantic difference is that 'yield' pauses your execution and gives control to the calling code, while 'await' pauses your execution and gives control to the promise. Completely different direction of control-passing. It so happens that you can use an async manager wrapped around your function to make the first look like the second, but that doesn't mean they're the same thing, and it doesn't mean that we want to adopt that kind of semantic for the language itself. ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
