What is functional programming?
In short: It is programming without mutation. If you want to write loops, use recursion! Or some abstraction upon recursion, like the `map` function.
The benefit is that functional programs don't have any unexpected side-effects, making them easier to reason about & test.
If you call a "pure" function you know that the only data it reads were those you passed into it, & the only data it writes is that which it returned back to you.
1/1.5!
I've personally quite enjoyed functional programming, and I'm building my own "Alonzo" targeted towards those who might not otherwise program.
I'm hoping that saying "there's only bricks, & (practically) all bricks are themselves defined in terms of bricks" will make programming more intuitive. In that there's less to learn!
1.5/1.5 Fin for today!

You might enjoy Racket and the closely-related How To Design Programs.
Racket is a mostly-functional language, and How To Design Programs teaches functional programming as the natural way to write code (without admitting that it's being very opinionated.)
