Hi Arash,

Thanks for your outstanding contribution; I just have one question here then we can merge this request.

Seems I made numerous mistakes while I was documenting this project. Thanks for being such a sharp-eyed contributor 🦅!

I was wondering why you added this .editorconfig file? I feel most java-script developers use this configuration file.

While, in python, we put static code analyzers' configurations into the setup.cfg file, and almost all of them respect this behavior.
