replaceChildren() provides a very convenient mechanism for emptying a document fragment of all its children. You call it on the document fragment without any argument specified:

let fragment = new DocumentFragment();
let div = document.createElement("div");
let p = document.createElement("p");
fragment.append(p);
fragment.prepend(div);

fragment.children; // HTMLCollection [<div>, <p>]

fragment.replaceChildren();

fragment.children; // HTMLCollection []

• DocumentFragment.prepend()
• DocumentFragment.append()
