getElementsByTagName() equivalent for textNodes

Question

Is there any way to get the collection of all textNode objects within a document?

getElementsByTagName() works great for Elements, but

Answer 1

after createTreeWalker is deprecated you can use

  /**
   * Get all text nodes under an element
   * @param {!Element} el
   * @return {Array}
   */
  function getTextNodes(el) {
    const iterator = document.createNodeIterator(el, NodeFilter.SHOW_TEXT);
    const textNodes = [];
    let currentTextNode;
    while ((currentTextNode = iterator.nextNode())) {
      textNodes.push(currentTextNode);
    }
    return textNodes;
  }
