This version works much better in terms of comprehension! I tested the code snippet in this StackBlitz example using the following script:

<script>
  const accordionCollapseElementList = document.querySelectorAll('#accordionExample .collapse')
  const accordionCollapseList = [...accordionCollapseElementList].map(accordionCollapseEl => new bootstrap.Collapse(accordionCollapseEl))
  console.log(accordionCollapseList)
</script>

The result is exactly as expected: the first accordion item is collapsed, while the other two are expanded.
