Noob clojure question. I have a list of items and I want to append a
subitem to one of them. They're currently unkeyed because I care about the
order and it seemed more intuitive that way.
(def items [{ :id 1 :subitems [] } { :id 2 :subitems [] }])
So let's say I want a new list where the second one has two a new subitem
would a map be appropriate, but only operate on the matching id?
; item-id and subitem in scope
(defn add-subitem-if-id-matches [item]
(if (= (item :id)
; return new item with additional subitem
; return unmodified item
)
and run that through a map? It seems to work, but I'm not sure if that's
the best way to go about doing it.
(map add-subitem-if-id-matches items) ; returns new list of items where
subitem has been added to one of them.
A more simple example.
'( '(1, "hello") '(2, "goodbye") )
Would I run something like this through a map if I wanted to only
map/modify certain elements like if the first element was 2 or even or
something?
'( '(1, "hello") '(2, "ack") )
