Chapter notes<br />
Chapter notes provide historical context, l<strong>in</strong>ks to further read<strong>in</strong>g, and additional discussion or<br />
connections to help tie the material we’ve covered <strong>in</strong> the book to the larger practice and research of<br />
the FP community. If you’re <strong>in</strong>terested, we encourage you to do some Wikipedia surf<strong>in</strong>g and further<br />
exploration us<strong>in</strong>g some of the content covered here as a branch<strong>in</strong>g-off po<strong>in</strong>t.<br />
Many of the chapter notes l<strong>in</strong>k to resources that use the Haskell language⁵. We recommend read<strong>in</strong>g<br />
the brief <strong>in</strong>troduction to Haskell, which gives an overview of Haskell for Scala programmers.<br />
A more up-to-date version of this content is available on the FPiS community Wiki.⁶<br />
Gett<strong>in</strong>g answers to your questions<br />
If you have any questions about the book, or about functional programm<strong>in</strong>g <strong>in</strong> Scala (or <strong>in</strong> general),<br />
here are some suggestions:<br />
• Ask on the scala-functional mail<strong>in</strong>g list⁷<br />
• Talk to Paul⁸ and Rúnar⁹ directly on Twitter.<br />
• For questions regard<strong>in</strong>g functional programm<strong>in</strong>g with the Scalaz library, ask on the Scalaz<br />
mail<strong>in</strong>g list¹⁰.<br />
• Post your question on the FPiS community Wiki.¹¹<br />
Notes on chapter 1: What is functional programm<strong>in</strong>g?<br />
See the Wikipedia articles on functional programm<strong>in</strong>g¹² and referential transparency¹³.<br />
Why functional programm<strong>in</strong>g matters<br />
In this chapter we highlight some of the benefits of functional programm<strong>in</strong>g. A classic article that<br />
gives some justification for FP is John Hughes’s Why Functional <strong>Programm<strong>in</strong>g</strong> Matters¹⁴.<br />
