How to wait for a Promise to resolve without using callbacks

Question

I have a function that returns a promise. How can I wait for the promise to resolve snd then restart the code execution without using the .then() callback? Or basically:

const returnValue = promiseFunc()
console.log(returnValue) // I want the promise to resolve before this executing

I know that this works:

promiseFunc().then(returnValue => {
    console.log(returnValue)
})

but I have code which looks a bit like this:

for (/*conditions*/) {
    // code
    promiseFunct()
    // code
}

I have no idea how to put that into a callback.
