These are my strings and their speeds at which they will be displayed

var typed = new Typed(".auto-input", {
        strings: ["Hi, blahblahblah.", "blahblahblah...", "...blahblahblah?"],
        typeSpeed: 75,
        backSpeed: 75,
        loop: true
    });

This is my code for when my checkbox is checked

var checkbox = document.getElementById('checkbox');

checkbox.addEventListener('change', () => {
  document.body.classList.toggle('dark');
});

I tried an if statement

if (document.body.classList.toggle('dark')) {
  typed.push(["lorem"]);
}

But then i realized, i think i need to select the "strings" in my "typed" vaiable. I'm not quite sure how to do that. I apologize in advance for any mistakes, this is my first question posted on StackOverflow.
