Eilenberg was an algebraic topologist and MacLane was an algebraist. Category Theory is a mathematical discipline with a wide range of applications in theoretical computer science. I would go as far as to argue that category theory is the kind of math that is particularly well suited for the minds of programmers. This book has a great approach to explaining Category Theory with examples in Haskell and C++, and probably there's no better way for having a grasp of monads. The category theory should also be viewed as more a close analogy to the programming problem, rather than an exact correspondence. This edition contains both Haskell and Scala code one after the other. Would recommend this book despite its shortcomings.

Wadler’s “Theorems for free!”) • But it’s scary and incomprehensible. Peter Dybjer. Category theory formalizes mathematical structure and its concepts in terms of a labeled directed graph called a category, whose nodes are called objects, and whose labelled directed edges are called arrows (or morphisms). Guess what? However, it is wonderfully concise and makes for a great reference, especially if you have a teacher or mentor who can help guide you through the concepts. These abstractions sometimes leak, especially in numerical code. In this course we explain how category theory—a branch of mathematics known for its ability to organize the key abstractions that structure much of the mathematical universe—has become useful for writing elegant and maintainable code. This is an ambitious book that dares to tackle concepts usually reserved for graduate Algebra courses and makes them presentable for those with a functional programming background. Libro un po' datato per apprendere le basi della teoria delle categorie. Afterward, I was a postdoc at the University of Michigan, ending in May 2015, when I left academia and became a programmer. Since my academic background is in Computer Science, I found this book very helpful in understand advanced functional programming topics as functors, monoid and monads. Reviewed in the United States on February 15, 2016. I recently worked through Bartosz Milewski’s excellent free book “Category Theory for Programmers.” The book is available online here and here.. The last is my own problem - much useful mathematics has been developed using Category Theory. The analog of a type checker would go even further by making sure that, once Romeo is declared a human being, he doesn’t sprout leaves or trap photons in his powerful gravitational field.”, https://github.com/hmemcpy/milewski-ctfp-pdf. I didn't complete the entire book (read until applicatives and Monads), used the book in conjunction with Bartosz video series on youtube and found it very useful to understand the theory behind. I strongly wanted to like this book more. Key words and phrases: Category theory, computing science. The "category theory for computer science" books are typically targeted at theoretical computer science students/researchers.
