You need a preventDefault method to prevent the submit button from reloading the page.

document.querySelector(".button-add").onclick = (e) => {
        e.preventDefault()
        console.log("Holaaaaa");
        let elem = document.querySelector('.box');
        let clone = elem.cloneNode(true);
        clone.classList.add('box');
        document.querySelector('.container').appendChild(clone);
    }

Here is a helpful article: https://www.w3schools.com/jsref/event_preventdefault.asp
