Anyone know of a good book or article that gives an overview of functional programming and answers the question of "Why Functional Programming", without going into details any one functional language?
It is also difficult to talk about concepts without some notation, and a notation is exactly what a programming provides (as well as other things)!
That said, several people have attempted to write about it. John Hughes' "Why Functional Programming Matters" is one that often comes up. There are a million versions of this floating around the web. Here is one: https://www.youtube.com/watch?v=bL-CcjKW1lw
I gave a talk on this topic, with examples in Scala: https://www.youtube.com/watch?v=bL-CcjKW1lw
This paper is about the idea of paradigm shifts in programming, and is beautiful and profound, though not about functional programming: https://www.dreamsongs.com/Files/Incommensurability.pdf

For me, Scala is much nicer for imperative/OOP than Java, in ways that aren't just skin deep.
