Answer 1

For example like this:

var readMoreBtn = document.querySelector(".js-btn-readmore"),
    readMoreContent = document.querySelector(".js-description-info");

readMoreBtn.addEventListener("click", function(event) {
    event.preventDefault();
    readMoreContent.classList.toggle("js-readmore-show");
    this.textContent = this.textContent === 'Подробнее' ? 'Скрыть' : 'Подробнее';
});

Why not google javascript toggle innerhtml? Moreover, the question is rather trivial and there should be many different answers.
