## verydisco-reverso
### Instructions
Create a `verydisco-reverso.mjs` script that:
- takes the name of a file (with extension) in argument
- read this file
- discover the content of this file by reversing it from the `very disco` mode
- print the result in console
For example:
- Reading the `verydisco` content of your `verydisco.txt` file would print `discovery` in console.
### Notions
- [Node file system: `readFile`](https://nodejs.org/api/fs.html#fs_fspromises_writefile_file_data_options)
<!-- and also Math.floors ? -->
<!--

- [Node path: `resolve`](https://nodejs.org/api/path.html#path_path_resolve_paths)
- [Node path: `join`](https://nodejs.org/api/path.html#path_path_join_paths)
