Gilded Rose Kata Angular 1

This is a very well known kata, and seeing this issue in a modern app might lead to do some refactor because you will see with more clarity what is the problem behind this kata. Seat back, relax and enjoy ;)

The algorithm

function updateQuality() {
  const items = _items;
  for (var i = 0; i < items.length; i++) {
    if (items[i].name != 'Aged Brie' && items[i].name != 'Backstage passes to a TAFKAL80ETC concert') {
      if (items[i].quality > 0) {
        if (items[i].name != 'Sulfuras, Hand of Ragnaros') {
          items[i].quality = items[i].quality - 1
        }
      }
    } else {
      if (items[i].quality < 50) {
        items[i].quality = items[i].quality + 1
        if (items[i].name == 'Backstage passes to a TAFKAL80ETC concert') {
          if (items[i].sell_in < 11) {
            if (items[i].quality < 50) {
              items[i].quality = items[i].quality + 1
            }
          }
          if (items[i].sell_in < 6) {
            if (items[i].quality < 50) {
              items[i].quality = items[i].quality + 1
            }
          }
        }
      }
