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"}

No repository files, tests, or entry points are mentioned; clarify whether this example should be added or revised in the project documentation, then verify the displayed result matches the requested map.
