I have 4 divs with the class of .btn applied to all of them. I want to console.log each button and only expect 4 items to be printed out but this is what was printed out:

0
1
2
3
entries
keys
values
forEach
length
item

And this is my code:

const btns = document.querySelectorAll(".btn");

for(let btn in btns){
    console.log(btn)
}

I want to eventually be able to call methods like getAttribute() on each button to apply different styles but it is not letting me.
