//Here is how you would use it, this is just an idea ofc. You can improve on it.
var likes = 0;
var liked = false;
button = document.getElementById("LikeButton");

function show() {
button.innerHTML = likes + " Likes";
}

button.onclick = function() {
if (liked === false) {
liked = true;
likes++;
show();
} else {
liked = false;
likes--;
show();
}
};
