I think there are more that scream loudly if they aren’t ...

function add_element(parent, name, objattrs, tagattrs, children = null)
  /* general routine for creating a new HTMLElement, initializing
    attributes, and attaching it to a parent element and attaching
    child elements, if specified. */
  /* I think objattrs and tagattrs are largely interchangeable ... */
  {
    const result = document.createElement(name)
    if (objattrs !== null)
      {
        for (const [name, value] of Object.entries(objattrs))
          {
            result[name] = value
          } /*for*/
      } /*if*/
    if (tagattrs !== null && tagattrs !== undefined)
      {
        for (const [name, value] of Object.entries(tagattrs))
          {
            const attr = document.createAttribute(name)
            attr.value = value
            result.attributes.setNamedItem(attr)
          } /*for*/
      } /*if*/
    if (children !== null)
      {
        for (const child of children)
          {
            result.appendChild(child)
          } /*for*/
      } /*if*/
    if (parent !== null)
      {
        parent.appendChild(result)
      } /*if*/
    return result
