hi .. can you explain how it can be converted to async / await to make it more readable ?

Using async and await, without chained should be like this:

async function doWork() {
const $getUserName = await getUserName()
const $getAge = await getAge($getUserName)
const $getDepartment = await getDepartment($getAge)
const $getEmployeeCode = await
await printInfo($getEmployeeCode)
}
doWork()
