Overview

• There is an interest in pure (mathematical) functions

  • Functions that some input and output but nothing else

• Immutable data

  • Data types cannot be changed in-place

• Less side effects

• Declarative

• Easier to verify

  • Can mathematically prove an implementation

Paradigm

The approach of asking programming questions that functional programmers take is much more overarching. [1] Examples are:

1. When designing an interactive program, they would ask: What is interaction?

2. When implementing Conway's Game of Life, they would ruminate on the meaning of life.

To a functional programmer, the essence of programming, per Milewski, is to take big problems and decompose them into smaller problems. Then create small solutions that can then be composed together to solve the big problem. [1]
