A tiny collection of DOM helpers for IE8+.

// IE8+
//
// Attempts to mirror $.before for htmlString and Elements.
//
// Portion of this method is a snippet from:
// http://youmightnotneedjquery.com/#before
//
function before(/* Element */ el, elementOrText) {
  if (typeof elementOrText === 'string') {
    el.insertAdjacentHTML('beforebegin', elementOrText);
  } else {
    // assumes node
    el.parentNode.insertBefore(elementOrText, el)
  }
}

module.exports = before;
