Error Messages

Read a caught error message.

error_messages.js

const code = "E2";
let message = "";

try {
  if (code !== "OK") {
    throw new Error(code);
  }
  message = "all clear";
} catch (error) {
  message = "handled:" + error.message;
}

console.log("code=" + code);
console.log("message=" + message);

error-messages Caught errors carry details such as a `message`. Programs usually convert those details into user-facing or log-facing strings.
