There is an issue you need to be aware , be careful if you hide the fact that this collection is "live". I mean this part from the docs
>An HTMLCollection in the HTML DOM is live; it is automatically updated when the underlying document is changed. For this reason it is a good idea to make a copy (eg. using Array.from) to iterate over if adding, moving, or removing nodes.
So you need something that will also be efficient and correct, not a 5 minutes implementation.
Same issue applies if you mutate array you're iterating over during iteration using those Array.prototype functions. This is just a general issue with any data structure.
