The purpose of hidden files
I am in the programming field for quite a long but a question raises when looking at this video: what is the purpose of hidden files?
I know some of them are used for configuration (.vimrc, .prettierrc and so on). But why do we hide them?
Is it some kind of a convention?
Yes, sure :) But for instance for .prettierrc or .eslint, you will remove them anyway if you delete the all folder. But I think I see what you say :)
