Because the information is coming from a table I don't know if I can change
it to look like that.
The information from the table looks like {:people ({:name "John" :age 25}
{:name "Harry" :age 23} {:name "Peter" :age 24})}
I was wondering if you could apply (into [] (map (-> class1 :people) [:name
:age])) to each of the {:name "Peter" :age "24"}, {:name "John" :age "25"},
{:name "Harry" :age "23"} and then put that into a vector so the final
vector is in the form
[["John" "25"]
["Harry" "23"]
["Peter" "24"]]
