Example + Live Practice
<script>
async function fetchPost() {
const response = await fetch("https://jsonplaceholder.typicode.com/posts/1", {
method: "GET",
headers: { "Accept": "application/json" },
});
console.log("Status:", response.status);
const data = await response.json();
console.log("Title:", data.title);
}
fetchPost();
// Axios example (if axios included in project):
// axios.get("https://jsonplaceholder.typicode.com/posts/1")
// .then((res) => console.log(res.status, res.data))
// .catch((err) => console.error(err));
