Add elements to existing jQuery set

Question

Considering we have

let existingSet = $();

How are newElements added to that set by means of jQuery?

existingSet = existingSet.add(newElements);

is not an option, because I need the reference to this object. As well as $.extend , because existingSet may not be empty.

$.merge documentation says that it accepts array-likes, but provides no further explanation of that, I'm not sure if it is suitable for jQuery objects.

Answer 1

why not use prepend to add to beginning of set, and append to add new elements to end of set ?

$(myset).append('<div>New element here</div>')

or

$(myset).prepend('<div>New element here</div>')
