Promises Fecth Async & Await

My JavaScript Code:

      // Fetch API requires a discussion of... 
// CallBacks, Promises, Thenables, and Async/Await

// abstract into functions

// maybe from a form
const getDataFromForm = () => {
    const requestObj = {
        firstName: "Bruce",
        lastName: "Lee",
        categories: ["nerdy"]
    };
    return requestObj;
}

const buildRequestUrl = (requestData) => {
    return `http://api.icndb.com/jokes/random?firstName=${requestData.firstName}&lastName=${requestData.lastName}&limitTo=${requestData.categories}`;
}

const requestJoke = async (url) => {
    const response = await fetch(url);
    const jsonResponse = await response.json();
    const joke = jsonResponse.value.joke;
    postJokeToPage(joke);
}

const postJokeToPage = (joke) => {
    console.log(joke);
}

// Procedural "workflow" function 
const processJokeRequest = async () => {
    const requestData = getDataFromForm();
    const requestUrl = buildRequestUrl(requestData);
    await requestJoke(requestUrl);
    console.log("finished");
}

processJokeRequest();
