Issue #9

The integration of yargs also provides a clear interface for specifying and documenting expected command-line options, making your script more user-friendly.

Using yargs makes your code more readable and maintainable. It separates the concerns of option parsing from the core logic of your script. Additionally, it allows users to easily understand and provide command-line options when running the script.

command: node index.js --saveFileAs output --csvFileName data
