Debugger

The Node.js debugger is an built-in tool that allows the users to pause the execution of the script and inspect variables, expressions to detect the errors. It is accessible using the command line and integrates well with the various debugging tools such as chrome DevTools and visual studio code.

When running the Node.js script, the errors occurs due to various reasons like syntax error, logical errors or runtime issues. By using this debugger we can analyse the script before deploying the applications.
