In clojure, how can I access and return a modified version of this collection
If I have a collection like this ({:A 1 :B 2 :Goal 5} {A:2 :B 4 :Goal 2}) is there a way I can iterate through the it and use assoc to change all :Goal to some other value, say 0?
So basically given the collection above and the key :Goal the function returns ({:A 1 :B 2 :Goal 0} {A:2 :B 4 :Goal 0})
Any help is appreciated.
Thanks

(let [A '({:A 1 :B 2 :Goal 5} {:A 2 :B 4 :Goal 2})]
(map #(assoc % :Goal 0) A))
or, if you are keen to use specter:
(let [A '({:A 1 :B 2 :Goal 5} {:A 2 :B 4 :Goal 2})]
(setval [ALL :Goal] 0 A))
