Description
Given a vector of maps
[{:key "document_env", :value "teste"} {:key "document_env2", :value "teste2"}]
How can I transform into a map like this:
{"document_env" "teste" "document_env2""teste2"}
There are multiple ways to do it.
First bind the data to a name for convienience
(def data [{:key "document_env", :value "teste"} {:key "document_env2", :value "teste2"}])
Using juxt
(into {} (map (juxt :key :value) data))
{"document_env" "teste", "document_env2" "teste2"}
Using for macro
(into {} (for [m data] [(:key m) (:value m)]))
{"document_env" "teste", "document_env2" "teste2"}
