How do you recover from an error in async/await in JavaScript?
Assign a fallback value in the catch block, then continue. For example: try { data = await fetch(); } catch { data = fallback; } render(data); // continues with fallback.

Use try/catch around the await calls. If any await rejects, the catch block runs with the rejection reason. try/catch also catches thrown errors inside the try block.
Yes. try/catch catches both promise rejections (from await) and thrown errors (from throw statements inside the try block). This is one advantage over .catch, which only catches promise rejections.
Use throw err in the catch block. This propagates the error to the caller. The caller can catch it with their own try/catch or let it propagate further.
