How to transform a list of maps

(def item1 ({:tag1 "val1" ,:tag2 "val2"} {:tag1 "val3" :tag2 "val2"}))

to vector of maps. The result should be

[{:tag1 "val1" ,:tag2 "val2"} {:tag1 "val3" :tag2 "val2"}]

Answer 1

I think what you are looking for is the vec function.

(def item1 '({:tag1 "val1" ,:tag2 "val2"} {:tag1 "val3" :tag2 "val2"}))
(vec item1)

;= [{:tag1 "val1", :tag2 "val2"} {:tag1 "val3", :tag2 "val2"}]

Note that you were missing a quote on your list of maps, otherwise since maps can take the function position, you are applying the second map to the first one (ie (map key) ).
