Front End Web Development Techdegree Student 13,307 PointsWhen is the promise being created by fetch()?
Looking at the following line by line:
btn.addEventListener('click', (event) => {
event.target.textContent = "Loading...";
fetch(astrosUrl)
.then(response => response.json())
.then(getProfiles)
.then(generateHTML)
.finally(() => event.target.remove());
});
Is the promise object being created after you pass astrosUrl to fetch() or is it being created by the .json() method.
