Summary:In the non-fiction work Old Times on the Mississippi, Mark Twain wrote, “When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I was 21, I was astonished at how much the old man had learned in seven years.” Functional programming is the old man who comes to the rescue when writing robust concurrent software. Functional programming treats computation as the evaluation of mathematical functions and avoids state and mutable data. It is a declarative programming paradigm, in which programming is done with expressions. The imperative style of programming emphasizes a sequence of operations characterized by iteration with loops, mutating data in place, and methods with side effects where the order of side effects is critical for the right effect.
