Short way to write IF Statement + Assignment of Async Function in one line

Question

Consider the code

let promiseEmployees;
const employeeFlag = DB.GetFromEMPDB(); // Goes to DAL and gets results


if (employeeFlag) {
    promiseEmployees = async () => {
            // Imp
            // ...
            // ...
            // ...
    };
}

Is it possible to rewrite this code in one line without writing literally the if (...) {...} ?

That's certainly possible. But why would you want to? It most certainly wont improve readability. — Ivar

What's wrong with if (DB.GetFromEMPDB()) promiseEmployees = async () => {...}? By the way, promiseEmployees won't be a promise with your code anyway, it will be an async function. (It would be a promise if you'd also call the function.) — CherryDT

This should work the following way:

const promiseEmployees = !DB.GetFromEMPDB()
  ? undefined
  : async () => {
      // Imp
    };

This I know , I'm looking for a shorter way...

How much shorter do you need? You could write no code. That would be shorter.
