使用循环在多维数组中追加内部对象

I have a multi-dimensional array of comment objects and I figured out how I can loop through the first-level of objects and then append them, but I am having a really hard time figuring out how to bring the replies along with the comments that have replies. My strategy was to use an "if" statement that checks to see if there's a reply, and then loops through the replies like I do the comments, but I think that the closest() function is the issue, I'm not quite sure how to access the DOM element that corresponds to that comment to use it as a selector. I think maybe another strategy would be to process the replies at the same time as the comments with one .each loop. Any help would be greatly appreciated!I have a multi-dimensional array of comment obj
