Exactly. I feel Clojure/Script too heavy to jump fully in, but it taught me about data structures, sequences, composition which lead me to Ramda.js.

This little functional library can be learnt in no time, and gives similar powers like Clojure, while learning Clojure and the ecosystem would take at least months.
