Grokking Functional Programming

Part 3. Applied functional programming

You have learned everything you need to know to easily write real-world applications using functional programming! As proof, in this part we will implement such a real-world application that uses Wikidata as a data source. We will apply all the techniques we learned earlier in the book and show that they can be used to create readable and maintainable code.

In chapter 11 we will introduce requirements for an application that generates a very peculiar travel guide. We will need to create an immutable-based data model and use proper types in signatures, including IO to integrate with Wikidata, use caching and multiple threads to make the application fast. We will wrap all of these concerns in pure functions ...
