Oh, just as shorthand: often to handle something like a default
cagegory.
Code would often look something like this (contrived made-up example):
@item_by_category = Post.all.group_by(&:category)
@expanded_posts = params[:expanded] ? @item_by_category[params
[:expanded]] : @item_by_category.first
I could have re-written our code but I've always liked the first/last
methods so I wrote the patch
