How To Correctly Resolve A Promise Within Promise Constructor

const setTimeoutProm = (delay) => new Promise(res => setTimeout(() => res(delay),delay)) I want to do something like, const asyncOpr = (delay) => { return new Promi

Solution 1:

No, actually the way you do it is an antipattern.

You can just return a promise from the function:

constasyncOpr = (delay) => { 
  return setTimeoutProm(delay);
 };

If needed, a Promise could also be returned from inside a .then:

doA()
   .then(() =>setTineoutProm(1000))
   .then(() =>doB());

Or it can also be awaited inside an async function:

asyncfunctionasyncOpr(delay) {
    //...await setTimeoutProm(delay);
    //...
 }
