all = [...document.querySelectorAll('.prop-column div')].filter(div => !div.matches('.hide, .call, .prop-value'))
obj = {}
current = ''

all.forEach(div => {
  try {
    if(div.matches('.delimiter')) {
      obj[div.textContent] = []
      current = div.textContent
    } else {
      obj[current].push({
        [div.querySelector('.call').textContent] : div.querySelector('.prop-value').textContent
      })
    }
  } catch {}
})

console.log(obj)

You can't put an array in a string element =) If you want to make an array an object, then it's already more complicated:

const arr = ['some'];

const props = ['something', 'more', '...'];

function createObjectFromArray(array) {
  let obj = {};
  array.map(itm => obj[itm] = itm);
  return obj;
}

function transformArrayToObject(arr, elementIndex, value) {
  if(!arr || isNaN(elementIndex) || !value) return {};
  const objectFromArr = createObjectFromArray(arr);
  objectFromArr[arr[elementIndex]] = value;
  return objectFromArr;
}

console.log(transformArrayToObject(arr, 0, props));
