DocumentFragment: prepend() method

The DocumentFragment.prepend() method inserts a set of Node objects or string objects before the first child of the document fragment. String objects are inserted as equivalent Text nodes.

This method prepends a child to a DocumentFragment. To prepend to an arbitrary element in the tree, see Element.prepend().

prepend(param1)
prepend(param1, param2)
prepend(param1, param2, /* …, */ paramN)

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>]
