Koa already supports async functions, so you can try them out today using babel.
Not too long ago we just wrote callbacks, then the Promise/A+ specification emerged followed by generator functions andnow the async functions.
Async functions let you write Promise-based code as if it were synchronous.
If you would like to master async functions, I recommend checking out the following resources:.
Async functions work much like generators, but they are not translated to generator functions. .
Keep in mind- Generators and async functions always return a specific type of object:.
Async functions more or less let you write sequenced JavaScript code, without wrapping all your logic in callbacks, generators, or promises.
In the example below,we use Webpack and Babel to compile ES Modules and async functions into vanilla JS, which can run in any browser.
We can also use async functions with loops and conditionals without much of a headache:.

It employs promises and async functions to rid apps of callback hell and simplify error handling.
Method handlers are async functions that get the request object as argument and return a promise that resolves to an object that describes the response.
When the async function is called, it returns with a Promise.
