File Permissions Lab

In this lab, you will be working with the fs module and the fs.fchmod() function in Node.js. The fs.fchmod() function allows you to modify the permissions of a file using the file descriptor. This has several practical use-cases such as making a file read-only or allowing execution for a script.

This lab will help you understand how the fs.fchmod() function works, the permissions in the octal representation for various use-cases, and how to handle any possible errors that may occur.

To complete this lab, you will need to correctly use the fs module and the fs.fchmod() function, to change the permissions of various files as per the given challenges.
