try / catch

Wrap JSON.parse on a possibly-malformed incoming message in a try/catch block, logging a friendly error instead of letting the whole script crash. try/catch lets you handle an operation that might throw without stopping every other part of the app.

🎯 Your Task

Please add the exact code shown in the light gray box below to your editor.Do not delete your previous code, just insert these new lines in the correct place!

const incomingMessage = "{ not valid json";

try {
  const parsed = JSON.parse(incomingMessage);
  console.log(parsed);
} catch (err) {
  console.log("Couldn't parse incoming message:", err.message);
}
