Promise and Async / Await

Example using a Promise

var getPosts = () => {
    fetch('/wp-json/wp/v2/posts')
        .then((response) => response.json())
        .then((json) => { console.log(json); });
};

Example using async / await

Note: await only works when inside an async function.

var getPosts = async () => {
    var response = await fetch('/wp-json/wp/v2/posts');
    var json = await response.json()
    console.log(json);
};
