JavaScript - async await

We can use the older technique of using fetch() to call an API asynchronously and also using the .then() method of that promise response object but there is a more modern approach.

The more modern way to consume promises in JavaScript is using await. By labeling the function with await and using async, we can eliminate the use of the .then() method. 


const url = 'https://api.github.com';

const FetchData = async () =>
{
    const resp = await fetch(url);
    const jsonData = await resp.json();
    console.log(jsonData);
    document.getElementById("demo").innerHTML =
    `
        ${jsonData.authorizations_url}<br />
        ${jsonData.code_search_url}<br />
        ${jsonData.emails_url}
    `;
};

window.onload = function ()
{
    FetchData();
}
