How to infer from the PUG mixin?

Question

Pug

Hey!
There is a large product mixin, with arrays. I can't figure out how to enter data for arrays in each call to such a mixin.
Maybe someone will tell

mixin product-item(notice, name, price, size, old, oldprice, img)
    +b.product-item
        +e.wrapper
            +e.compare
                +e.add.--compare(href="javascript:void(0);" title="")
                    include ui-kit/icon.pug
                    +icon("compare").--product-item
            +e.favorites
                +e.add.--favorites(href="javascript:void(0);" title="")
                    include ui-kit/icon.pug
                    +icon("favorites").--product-item
            if notice == 'vip'
                include ui-kit/label.pug
                +label('vip').--vip
            else if notice == 'hit'
                include ui-kit/label.pug
                +label('хит').--hit
            else if notice == 'new'
                include ui-kit/label.pug
                +label('new').--new
            else if notice == 'sale'
                include ui-kit/label.pug
                +label('%').--sale
            +b.button.--product-quck.js-qick-view(href="javascript:void(0);" title=name) быстрый просмотр

            +e.info
                +e.name #{name}
                +e.size #{size}
                +e.hidden-info
                    +e.size-change
                        include ui-kit/hr.pug
                        +hr().--product-item
                        include ui-kit/size-list.pug
                        //это вывести отдельно
                        +size-list({'items': [{
                                "textLabel": "XL",

                            }
                        ]}).--square.--product-item
                   //это вывести отдельно
                    +characteristic-info({'items': [{
                            'title': 'Ш х В х Г',
                            'definition': '40 x 55 x 20/24 см'
                        },
                        {
                            'title': 'Объем',
                            'definition': '38/43 л'

Conclusion:
