Answer / Himanshu Shekhar
Exit codes in Node.js are numbers that a JavaScript program returns when it terminates, indicating its status. Common exit codes include:
- 0: Successful exit (default exit code if no error occurs).
- 1: An error occurred, but the problem can be solved without losing data (e.g., an argument was passed incorrectly).
- 255: System error (operating system specific).
- 8: Operational error (e.g., permission denied or resource unavailable).
