function debounce(fn, delay) {
  var timer = null;
  return function () {
    var context = this, args = arguments;
    clearTimeout(timer);
    timer = setTimeout(function () {
      fn.apply(context, args);
    }, delay);
  };
}

// usage
// removing the class from the body inside a debounce
var debouncedA = debounce(function() {
  theBody.classList.remove("OffCanvas-Active");
}, 250);
