How to select last letter of text using js loop?

Question

JavaScript

How do I select (iterate through) the last letter of a text using a loop?
There is such a structure:

Answer 1

Do you need a cycle? You can do this: But if you need a loop, then for in is not very suitable in my opinion.
let endChar = $("h1").text().substr(-1);

let text = $("h1").text();

for(let i = 0; i < text.length; i++){
  if (i == text.length - 1) console.log(text[i]);
}
