Answer 1

In fact, it is not very convenient due to the fact that the array needs to be lined up in one line. Maybe someone else can suggest a solution.

each item in newsList
            li            
                a #{item.name}
                each subitem in item.sub
                    ul
                        li
                            a #{subitem}

I continued to dig and with mixins it turns out more beautiful:

- var newsList = [{name : 'Пункт 1', sub: ['Пункт 1.1', 'Пункт 1.2', 'Пункт 1.3', 'Пункт 1.4']}] 
- var newsList2 = [{name : 'Пункт 2', sub: ['Пункт 2.1', 'Пункт 2.2', 'Пункт 2.3', 'Пункт 2.4']}]

mixin list(items)
            ul
                each item in items
                    li
                        a #{item.name}
                        each subitem in item.sub
                        ul
                            li
                                a #{subitem}

And we call mixins:

+list(newsList)
+list(newsList2)

But perhaps you can somehow make it even more beautiful

Added:
and

each item in menu
        +list(item)

I hope it will be useful to someone

Answer 2

The array does not have to be in 1 row

- 
 var newsList = [
 {name : 'Пункт 1', sub: ['Пункт 1.1', 'Пункт 1.2', 'Пункт 1.3', 'Пункт 1.4']}, 
 {name : 'Пункт 2', sub: ['Пункт 2.1', 'Пункт 2.2', 'Пункт 2.3', 'Пункт 2.4']}]

or so

- var newsList = [
- {name : 'Пункт 1', sub: ['Пункт 1.1', 'Пункт 1.2', 'Пункт 1.3', 'Пункт 1.4']}, 
- {name : 'Пункт 2', sub: ['Пункт 2.1', 'Пункт 2.2', 'Пункт 2.3', 'Пункт 2.4']}]

As a result, the first option is shorter

each item in newsList
            li            
                a #{item.name}
                each subitem in item.sub
                    ul
                        li
                            a #{subitem}
