Я застрял на данный момент. Я пытаюсь передать логическое значение в действие, которое затем будет использовать регистр (FILTER_SIZE) внутри редуктора, который либо устанавливает значение в массиве display_clothing для элементов с тем же sizeID, либо очищает массив display_clothing, что приводит к возврату моей страницы Item вернуться к отображению предметов одежды из массива одежды в пределах указанного, а не отфильтрованных предметов в display_clothing.
Кажется, что Filter_clothes не меняет своего значения после оператора if-else на основе имеющихся у меня console.logs , Примечание. Я сделал в фильтре значение Filter_clothes, но во время оператора if-else получил недопустимую ошибку присваивания, поэтому вместо него использовал let. (Если честно, я не уверен, почему это не сработало, поскольку я сделал что-то подобное в случае ПОКУПКИ, используя вместо этого const)

Если у вас есть какие-либо предложения по поводу того, что я должен попробовать, буду признателен. Я бьюсь головой о стену, пытаясь понять это.
Спасибо!
