Pro tip: you can't reimplement this in Scheme.
var list = document.getElementsByClassName('num');
for(var i = 0; i < list.length; i++){
var num = list[i].textContent*1,
isDub = num < 100 && num % 11 == 0,
res = document.createElement('span')
res.className = 'dubcheck dubscheck-'+(isDub?'yes':'no')
res.textContent = isDub?'✔ Dubs check\'d!':'✘'
res.style.color = isDub?'green':'red'
list[i].parentNode.appendChild(res)
}
