How to read an array inside another array in an ” Json object” -> Jade/PUG.js

I’m trying to “create” a template using “Json” in Pug, but there is a point where I need to put much Information. But the problem for me becomes where I need to read an element deeply inside.

  var SuperSlidersInfo = {
      'numero': '4',
      'sectionName': 'Dignidad',
      'video': true,
      'youtube': [
        'idVideo',
        'idVideo2',
        ],
      'notes':[
        ['prueba1', 'prueba2'],
        ['segundo1', 'segundo2', 'segundo3'],
      ],
      'img': [
        'NombreImagen',
        'NombreImagen2',
        ],
      'extension': 'jpg',
      'titulo': [
        'Titulo',
        ],
      'parrafo': [
        'Texto',
      ]}

 .container-pc
    .container-sliderAutomatico.no-phone
      div(id=`sliderAutomatico${SuperSlidersInfo.numero}` class= SuperSlidersInfo.video ? "dosVideos-container" : "otraCosa").sliderAutomatico
        each imgName, index in SuperSlidersInfo.img
          //- div(class= SuperSlidersInfo.video ? "dosVideos").sliderAutomatico__section
          div(class= SuperSlidersInfo.video ? "dosVideos" : "otraCosa").sliderAutomatico__section
            .swiper-content
              if SuperSlidersInfo.video
                .section_videoContainer
                  a(href=`#video${SuperSlidersInfo.sectionName}${index}`).section_videoThumbnail--Container
                    img(src=`${imgURL}${SuperSlidersInfo.sectionName}${index + 1}.${SuperSlidersInfo.extension}`, alt="")
                  h3.swiper-content_titulo= `${SuperSlidersInfo.titulo[index]}`
                  .section_video--notes
                    //- -----------------
                    //- Problem
                    //- -----------------
                    //- the "a" below works, but I need to "create" and each, or for, or any loop for to put all the elements in that especific array. 
                    //- a(href=`${SuperSlidersInfo.notes[index]}`).section_video--note
                    
                    //- The "each" below it suppose to works. But when I put the "[index]" it brokes..
                    each note, noteIndex in SuperSlidersInfo.notes[index]
                      a(href=`${note}`).section_video--note

For general elements it works well. But when I need to read the “notes”. It’s impossible por me.

But when I put each note, noteIndex in SuperSlidersInfo.notes[index] everything is broken…

So I need to read the “elements” that “note” has in its array…

//- Works well
each note, noteIndex in SuperSlidersInfo.notes
//- It's Broke
each note, noteIndex in SuperSlidersInfo.notes[index]

the index is from the each that exist almost at top of the code
