All the information

The os module is a very nifty little module that allows us to get information about the OS. While it has a lot of operating system-related utility methods and properties, we will just look at a few common ones. Run the code below and see if you understand what each output means.

console.log("Release number:", os.release(), "\n")
console.log("User info:", os.userInfo(), "\n")
