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 (...) {...} ?

Answer 1

This should work the following way:

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