Where is my mistake?

Question

function setText() {
var a = document.getElementById("demo");
var arr = a.childNodes;
for (var x=0; x<arr.length;x++){
arr[0].innerHTML = "its me"
}
}

setTimeout(setText(), 120)

Answer 1

In the last line....
You no need to put parenthesis after function name...

Answer 2

Can you tell what error are you getting?

Answer 3

Recheck the loop, you always use 0 (zero) as element index there. I'm guessing you meant to pass <x> instead like this 👇

arr[x].innerHTML = "it's me";

(Corrected - Thanks to Ja Play)

Answer 4

I think it should be
arr[x].innerHTML = „its me“;
