Replace selector with array item

I would like to archive that I have an Array, with 3-4 Items and then I want to itterate throw all of them and change the selector in the function with the items of the array.

let items = ['Name','Person,'New']

then my function

$('.btn').on("click", function(){do smth});

and then the foreach .btn should be like name or person, and I want maybe to add late more Items to the array. How should I do it?
