Re: Creating a hashmap
And a completely different approach:
(into {} (map-indexed #(vector (inc %1) %2) ["a" "b" "c"]))

Re: Creating a hashmap
Awesome... I'm studying lists manipulation. Solidifying this concept. The basic in Clojure, in my point of view. Thanks again.

Creating a hashmap
Hello all, I'm studying a little bit of Clojure and facing a doubt here. I hava a list (a b c) and want to create a hashmap using the elements from this list. The keys will be a sequential number, and the values will be the values from the previous list. 1. list: (a b c) 2. desired hashmap: (hash-map 1 "a" 2 "b" 3 "c") How can I achieve this in a idiomatic functional way? Cheers. And thank you for your attention. -- christian -- You received this message because you are subscribed to the Google Groups "Clojure" group.
