Рейтинг 5 звезд несколько блоков без jQuery
Есть код, на рейтинг, все рабочее но нужен рефакторинг, - упростить и сократить js. Чтобы работали все блоки приходится писать 4 функции и менять только 1 переменную внутри них, кто может помочь оптимизоровать и сократить до 1 функции с перебором или любым другим методом?
Благодарю за любые комментарии)

Спасибо, поправил.
Если не затруднит еще просьба - так же и сократить беду с Хтмл чтоб на js он создавался реактивно без перезагрузки. Вот эта беда с классом .rating и .rating-item. (чтоб уже комплект был полный) |
