Honestly, just use axios. Fetch is a pain for JSON.
But if you’re stuck with fetch:
1. Check for `Content-Type: application/json` in headers.
2. Try-catch the .json() call—it throws if the JSON is invalid.
3. Some APIs wrap JSON in a weird format. Look for a `data` property or something.
Debugging tip: `console.log(typeof response)` to see if it’s already parsed or not.
