Hello I have such data
[ [ "tom" 23 ] [ "ann" 4434 ] [ "tom" 1234 ] ["mike" 34 ] ]
I would like to sort these data so finally i got
[ [ "ann" 4434 ] ["mike" 34 ] [ "tom" 23 ] [ "tom" 1234 ] ]
note that i don't care the order between "tom" keys (1234 can be
before 23)
I have seen sort-by but I can't find tutorial how to use keyfn
[ [ "tom" 23 ] [ "ann" 4434 ] [ "tom" 1234 ] ["mike" 34 ] ]

OK. I have figured it out. I just looked into core.clj and noticed that keyfn is a function which know how to get a value from an element in a collection. That value is just compared with other.
