Proposal Description:
Async Functions for ECMAScript
The introduction of Promises and Generators in ECMAScript presents an opportunity to dramatically improve the language-level model for writing asynchronous code in ECMAScript. The spec text can be found here.
This proposal is implemented in a regenerator which can compile ES5 code containing async and await down to vanilla ES5 to run in existing browsers and runtimes.
This repo contains a complete example using a large number of the features of the proposal. To run this example:
npm install
regenerator -r server.asyncawait.js | node
