--watch

The --watch flag in Node.js is a powerful feature introduced in Node.js version 19 that enables automatic reloading of your Node.js application whenever changes are detected in the specified files.

Here's How it works:

• You run your Node.js script with the --watch flag: $ node --watch your_script.js
• Node.js starts watching the specified file (or directory) for changes.
• Whenever a change is detected, Node.js automatically restarts the script
