This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.
The after() method of the CharacterData interface inserts a set of Node objects or strings in the children list of the object's parent, just after the object itself.
Strings are inserted as Text nodes; the string is being passed as argument to the Text() constructor.
after(...nodes)
None (undefined).
HierarchyRequestError DOMException
Thrown when the new nodes cannot be inserted at the specified point in the hierarchy, that is if one of the following conditions is met:
CharacterData node.DocumentFragment, a DocumentType, an Element, or a CharacterData.CharacterData node is actually a Text node, and its parent is a Document.CharacterData node is a Document and one of the nodes to insert is a DocumentFragment with more than one Element child, or that has a Text child.The after() method allows you to insert new nodes after a CharacterData node.
const h1TextNode = document.querySelector("h1").firstChild;
h1TextNode.after(" #h1");
h1TextNode.parentElement.childNodes;
// NodeList [#text "CharacterData.after()", #text " #h1"]
h1TextNode.data;
// "CharacterData.after()"
Note: If you rather want to append text to the current node, the appendData() method lets you append to the current node's data.
