Async in Practice

Async/await shines when working with real APIs using fetch(). The pattern is consistent: await the fetch, await the JSON parse, handle errors in try/catch.

async function getPost(id) {
  try {
    const res = await fetch(`https://jsonplaceholder.typicode.com/posts/${id}`);
    const data = await res.json();
    return data.title;
  } catch (err) {
    return "Failed to load";
  }
}

FINAL CHALLENGE

Write an async function that simulates a database lookup by awaiting Promise.resolve({ username: "coder99" }), then prints the username.

Need a hint?

Await the Promise and destructure: const { username } = await Promise.resolve({...}).

Expected Output:

coder99
