Javascript in TypeWriter Effect

I try to create a typeWriter effect using Javascript. It done perfectly, but it cannot type ‘<‘ character. I don’t know how to fix it

My code is:

let other = document.getElementById('other');
let txt = "Hello World <br> this typing effect.";
let i = 0;
function typeWriter() {
    if (i < txt.length) {
      other.innerHTML += txt.charAt(i); i++;
      setTimeout(typeWriter, 10);
      window.scrollTo(0, document.body.scrollHeight);
    }
}

typeWriter();
<h1 id='other'></h1>

I hope the result like:

Hello World
this typing effect.

Actual result I get:

Hello World <br> this typing effect.

Please give me some clue. Thanks in advance
