Status Codes (200, 400, 401, 404, 500)

Every API response includes a status code that tells you if the request succeeded or failed. **Common codes:** ``` 200: OK (success) 201: Created (new resource made) 400: Bad Request (you sent wrong data) 401: Unauthorized (not logged in) 403: Forbidden (logged in but no permission) 404: Not Found (resource doesn't exist) 500: Internal Server Error (something broke on the server) ```

const response = await fetch('/api/users/999')

if (response.status === 404) {
  console.log("User not found")
} else if (response.status === 200) {
  const user = await response.json()
  console.log(user)
}
