# Functional Programming For Dummies

Author:

## Overview

Your guide to the functional programming paradigm

Functional programming mainly sees use in math computations, including those used in Artificial Intelligence and gaming. This programming paradigm makes algorithms used for math calculations easier to understand and provides a concise method of coding algorithms by people who aren't developers. Current books on the market have a significant learning curve because they're written for developers, by developers—until now.

Functional Programming for Dummies explores the differences between the pure (as represented by the Haskell language) and impure (as represented by the Python language) approaches to functional programming for readers just like you. The pure approach is best suited to researchers who have no desire to create production code but do need to test algorithms fully and demonstrate

their usefulness to peers. The impure approach is best suited to production environments because it's possible to mix coding paradigms in a single application to produce a result more quickly. Functional Programming For Dummies uses this two-pronged approach to give you an all-in-one approach to a coding methodology that can otherwise be hard to grasp.

• Learn pure and impure when it comes to coding
• Dive into the processes that most functional programmers use to derive, analyze and prove the worth of algorithms
• Benefit from examples that are provided in both Python and Haskell
• Glean the expertise of an expert author who has written some of the market-leading programming books to date

If you’re ready to massage data to understand how things work in new ways, you’ve come to the right place!

Functional Programming For Dummies Cheat Sheet

Using functional programming techniques can make you incredibly efficient when solving certain problems or when you need to make full use of multiprocessing techniques to ensure that you get maximum benefit from each processor (or core). The functional programming paradigm supports the concept of pure languages (such as Haskell, which uses only functional techniques) and impure languages (such as Python, which actually supports multiple programming paradigms). In addition, functional programming has a strong math basis: every line of code is actually an expression, not a procedure, as in many other paradigms. This cheat sheet helps you understand these differences from other paradigms to enhance your functional programming experience.
