The article is filled with "unnecessary methods and such" , because you reffed to the article.
If you mean jQuery , then maybe the functions you don't use others use, give some examples , the most I use daily are attr,css, find, parent, wrap,unwrap,parents,each, filter,toArray, remove, append, after etc (my project gets a ton of possible broken html or html with garbage and I clean it up)
As of writing this comment the account in question is only 1 hour old. Maybe there should be some kind of time limit before account can comment. Anyway the account is obviously a throwaway created to troll this thread. Just ignore it.
