### Instructions

|
|
|
|
Your very favorite person's birthday is coming soon. So you've decided to
|
|
|
|
|
organize a very special party 🥳🪅🎤
|
|
|
|
|
|
|
|
|
|
Invitations have been sent for a while...
|
|
|
|
|
|
|
|
|
|
Good news: answers are back! Psst: Sorry buddy, we didn't count it, you've been
|
|
|
|
|
too generous. But we saved every one of them as a file in a special directory for
|
|
|
|
|
you. Have fun!
|
|
|
|
|
|
|
|
|
|
Create a `tell-me-how-many.mjs` script that:
|
|
|
|
|
|
|
|
|
|
- Take a relative or absolute directory path as argument from the command line.
|
|
|
|
|
- Read this directory path.
|
|
|
|
|
- Get the number of entries in this directory.
|
|
|
|
|
- Print the result in console.
|
|
|
|
|
|
|
|
|
|
If there is no argument passed, the script must execute itself in the current
|
|
|
|
|
directory
|
|
|
|
|
|
|
|
|
|
