if(window.localStorage.getItem('count')){
count = window.localStorage.getItem('count')
display.innerHTML = count;
} else {
window.localStorage.setItem('count', 0)

}
window.localStorage.setItem("on_load_counter", count);
button.onclick = function(){
count++;
window.localStorage.setItem("count", count)
display.innerHTML = count;
