Is it possible to append an element to a JavaScript nodeList?

Question

I\'m generating content dynamically, so I\'m often ending up with documentFragments which I\'m querying using querySelectorAll or querySelector

Answer 1

Unlike previously described element selection methods, the NodeList returned by querySelectorAll()is not live: it holds the elements that match the selector at the time the method was invoked, but it does not update as the document changes. ^[1]

The NodeList in this case is not alive, so if you add/remove anything to/from it, then it won't have any effect on the document structure.

A NodeList is a read-only array-like object. ^[1]
