Async/await in web browser or in node.js?

Question

Is there any attempt to bring async/await feature from C# 5.0 to any language which can be compiled to JavaScript (such as CoffeScript)? (So it can be used

Answer 1

Javascript is providing async-await feature with ECMA 7. Now all asynchronous function can be awaited by promisifying them and waiting for promise to resolve. Most of the asynchronous functions like DB calls, API calls, fs and events are returning promise now in Javascript and nodeJs. Now with async-await code is more cleaner, understandable, debugged.

Example

function timeout(){
  return new Promise( resolve => {
    setTimeout(function(){
      resolve(true);
    }, 5000);
  });
}

async function f(){
    let result = await timeout();
}
