}$lookup — joins the posts collection on _id → authorId.$unwind — flattens $posts into one document per element.$group — groups by "$_id" and aggregates author, averageViews.$project — returns only author, averageViews.$group, author takes the first value in the group, averageViews averages $posts.views — one output document per distinct "$_id".Write this in plain English instead.
