I thought the same thing. > Surely you could query the DOM for this. A better solution, in this case, is to let the backend developers mark the last user comment in the JSON they return. Backend developers have direct access to the database, which means they may be able to optimize the code. Then no client-side work has to be done at all, in this case. Look, I know what I am, I'm no fancy-pants silicon valley guru here. But what is described in this example is primarily a client-side function. So I think the wording for this is "a different solution" at minimum. Better? Meh. Will that new backend query ever serve any purpose other than facilitating this frontend feature? Perhaps instead of adhering to a "let's not query the DOM" at all costs, ask yourself what exactly you are complicating and for what gain.
