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.

この issue には、ソースファイル、テスト、コンパイラのエントリポイントが記載されていません。まず、TypeScript が ES6 ターゲット向けに async/await をどのように変換するかを追跡し、要求されたジェネレータ出力と現在の ES6 出力を比較してください。明確に定義されたコンパイラオプションによって要求された出力が生成され、既存のターゲットや動作を壊さないことが完了の条件です。
