### Instructions
|
||
|
|
|
||
|
|
Your very special partner's birthday is coming soon. So you've decided to organise a very special party. Invitations has been sent for a while... and good news: answers are back. We didn't count it, you've been too generous. But we saved every one of them as a file in a special folder for you. Have fun!
|
||
|
|
|
||
|
|
Create a `tell-me-how-many.mjs` script that:
|
||
|
|
- takes a relative or absolute folder path as argument from the command line
|
||
|
|
- read this directory path
|
||
|
|
- get the number of entries in this folder
|
||
|
|
- print the result in console
|
||
|
|
|
||
|
