Are you a relative newbie at functional programming? Do you have about a month? Then I highly recommend Prof. Dan Grossman's free online course: https://www.coursera.org/learn/programming-languages/

He teaches the syntax, semantics, and idioms of ML-style typed functional programming using the Standard ML language as a teaching vehicle. His explanations and course progression are really good. It will open your eyes to FP.
