node.js - Wrapping promise in async/await -

i'm struggling bit async/await , returning value promise.

function test () {   return new promise((resolve, reject) => {     resolve('hello')   }) }   async function c() {   await test() } 

as understood things should able value doing:

console.log(c()) 

but missing point here returns promise. shouldn't print "hello"? on similar note unclear whether callback needs converted promise before wrapping in async/await?

no, async functions return promises. they're not magically running asynchronous code synchronously - rather reverse, turn synchronous-looking code (albeit speckled await keywords) asynchronously running one.

you can result value inside asynchronous function:

async function c() {   const result = await test()   console.log(result);   return 'world'; } c().then(console.log); 

i unclear whether callback needs converted promise before wrapping in async/await?

yes, can await promises. see how convert existing callback api promises? how conversion.
