Node.js · Junior · Question 67 of 75

How do you catch an error from an awaited promise?

async function load() {
  const data = await readFile("config.json", "utf8");
  return JSON.parse(data);
}

✓Correct answer: Wrap the code in try { ... } catch (err) { ... }
2Errors in async functions can't be caught
3Add .error() after the function

Explanation

Inside an async function, await turns a rejection into a thrown error, so a normal try/catch works. Callers can also use load().catch(...).
