Have a look at our insertAdjacentText.html demo on GitHub (see the source code too.) Here we have a simple paragraph. You can enter some text into the form element, then press the Insert before and Insert after buttons to insert it before or after the existing paragraph text using insertAdjacentText(). Note that the existing text node is not added to further text nodes are created containing the new additions.
