#4The moment I started using async await (with babel) combined with the new fetch API so many libraries got obsolete.
Getting data is as easy as:
async function main () {
try {
const res = await fetch('https://api.github.com/orgs/facebook');
const json = await res.json();
console.log(json);
} catch (e) {
// handle error
}
}

#5This news is almost as important as the rest of ES2015 being implemented in Webkit.
async/await is the final piece in the puzzle of providing real solutions to callback hell in JavaScript.

#6> [esnext] prototype runtime implementation for async functions
Well, it claims to be a prototype. Can anyone from the team comment?
Quite exciting in any case!

#7The moment I started using async await (with babel) combined with the new fetch API so many libraries got obsolete. Getting data is as easy as: async function main () { try { const res = await fetch('https://api.github.com/orgs/facebook'); const json = await res.json(); console.log(json); } catch (e) { // handle error } } So I am quite happy when this lands in modern browsers asap.
Is the syntax composable? Can I do
const json = await (await fetch(https://api.github.com/orgs/facebook')).json();

yeah that works, your statement is fine

What you asked for is whether `await` is idempotent. No it isn't. The "argument" to `await` is a Promise, and the "return value" of it is the resolved value of the Promise (i.e. `Promise#then`).
EDIT: I missed the `.json()` part, but I suppose it doesn't return a Promise, no?
