1,053 PointsI'm getting promise status as fullfilled wherein , in the video it says resolved can you please explain the same?
const astrosUrl = 'http://api.open-notify.org/astros.json'; const wikiUrl = 'https://en.wikipedia.org/api/rest_v1/page/summary/'; const peopleList = document.getElementById('people'); const btn = document.querySelector('button');
function getJSON(url) { return new Promise((resolve, reject) => { const xhr = new XMLHttpRequest(); xhr.open('GET', url); xhr.onload = () => { if (xhr.status === 200) { let data = JSON.parse(xhr.responseText); resolve(data); } else { reject(Error(xhr.statusText)); } }; xhr.onerror = () => reject(Error('A network error')); xhr.send(); });
}
// Generate the markup for each profile
function generateHTML(data) {
const section = document.createElement('section');
peopleList.appendChild(section);
// Check if request returns a 'standard' page from Wiki
if (data.type === 'standard') {
section.innerHTML =
<div class="img-div">
<img src=${data.thumbnail.source}>
</div>
<div class="content-div">
<h2>${data.title}</h2>
<p>${data.description}</p>
<p>${data.extract}</p>
</div>
;
} else {
section.innerHTML =
<div class="img-div">
<img src="img/profile.jpg" alt="ocean clouds seen from space">
</div>
<div class="content-div">
<h2>${data.title}</h2>
<p>Results unavailable for ${data.title}</p>
${data.extract_html}
</div>
;
}
}
function getProfiles(json) { const profiles = json.people.map(person => { return getJSON(wikiUrl + person.name); }); return profiles; }
btn.addEventListener('click', (event) => { getJSON(astrosUrl) .then(getProfiles) .then(data => console.log(data)) .catch(err => console.log(err)) event.target.remove();
});

If successful, it is also said to be "fulfilled". The other possibility is that it was "rejected".
