Using Debugger?

Node.js includes a built-in debugger that can be activated with the --inspect flag or the debugger keyword in code. It lets you pause execution, step through code, and inspect variables at runtime using Chrome DevTools or a compatible IDE. Using a debugger is more efficient than adding console.log statements throughout the code.
