Does try/catch with await catch both rejections and throws in JavaScript?
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 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.
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 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.
