This post was written by Michael Dawson who is a Node.js Runtime Tech Dev @ IBM, #nodejs collaborator and CTC member. He originally posted this piece on the Nodejs @ IBM blog. SummaryChanges are coming to Errors thrown by the Node.js runtime. These changes started showing up in Node.js 8 and will continue to flow in during Version 9. This will impact any user whose code parses the message strings.

Node.js script won't exit if there's callbacks left in the main event loop. While one could forcefully terminate the script by calling process.exit() or throwing exceptions, it is recommended to let the script terminate "naturally", by always doing proper cleanup.
