Transpiling async/await to generators instead of es6-Generator-function for es6

async await es6 transpile generator

Suggestion

If there was a compile option that i can tell the compiler to emit generators instead of es6-Generator-function when targeting es6.

Use Cases

I have to use 3rd-party libs that implemented in es6，so targeting es5 will not work. But i can't write code with async/await when targeting es6 because the platform on which to run the app dose not support yield/funtion* (but other es6 features's ok).

Examples

Checklist

I try Babel and regenerator, all of them transpile es6 code into es5(or other version), but then I can't use 3rd-party libs. Work round is applying transpilation on libs too.

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

El issue no menciona archivos fuente, pruebas ni puntos de entrada del compilador. Empieza por rastrear cómo TypeScript transforma async/await para un destino ES6 y compara la salida del generador solicitada con la salida ES6 actual. Se considera terminado cuando una opción del compilador claramente definida produce la salida solicitada sin romper los destinos ni el comportamiento existentes.
