Помощь Мне нужно использовать localalstorage для сохранения имени, счета и даты игрока в браузере и отображения 5 самых высоких результатов в таблице. Сохранить и возобновить позже вариант. Таблица лидеров с наибольшим количеством очков, полученных в игре. Самые высокие оценки для игры должны быть доступны только для браузера на компьютере. Имя игрока, полученный счет и достигнутая дата должны отображаться в таблице лидеров.
