JavaScript
Fetch JSON from an API
fetch returns a promise; check response.ok before reading the JSON.
Example
javascript
async function getUser() { // a tiny stand-in for fetch so this runs anywhere const fakeFetch = async () => ({ ok: true, json: async () => ({ name: "Ada" }) }); const res = await fakeFetch("/api/user"); if (!res.ok) throw new Error("Request failed"); return res.json(); } getUser().then((u) => console.log(u.name));
