Error Messages

This video tutorial covers how to handle errors in Node.js by intentionally breaking a program to generate an error message. It explains how to analyze the error message and stack trace to identify the source of the problem. The tutorial also introduces the use of Node.js debugger tools and emphasizes the importance of building debugging skills over time. The video concludes with a brief mention of upcoming topics on asynchronous development.
