Functional Programming Lecture Notes by David Walker

Functional Programming by Loyola Marymount University

This is a resource provided by Loyola Marymount University on functional programming. It starts with a basic explanation and goes further into how one can make a shift from imperative programming to functional. The key topics it covers are higher-order functions, which are the backbone for doing functional programming in order to write abstract code reuse. This paper describes closures and purity, including side effects, in detail to apprise the reader about the value of immutability and functional purity. It describes both the functional and object-oriented programming paradigms, then it points to point-free programming, and concludes with an overview of the functional programming landscape. This should be a good reference for students and practitioners alike who want to know about the basics in functional programming and its theoretical underpinnings.

Functional Programming Lecture Notes by David Walker

David Walker's 'Functional Programming Lecture Notes' give quite an extended introduction to functional programming using OCaml. The notes introduce the reader to the very basics of OCaml and simple manipulations of data, from thinking in recursion to problem-solving. It covers Polymorphism and Higher-Order programming, commonly referred to as PolyHO. It will discuss functions operating on other functions and even data. Pipelines and datatypes have been explained purely from functional programming paradigms. It first introduces the functional evaluation model and functional space model, thereby introducing the reader to the theoretical points of view of functional programming. Equational reasoning, modules, functors, and modular reasoning are other topics treated within this context, while more practical aspects concern mutable data structures, threads, and parallel complexity models. This book will no doubt be very useful to those readers who would wish to become acquainted with both the theory and practice of functional programming.

Introduction to Functional Programming

These lecture notes by Piyush P Kurur elaborates on various functional programming topics in depth. The contents of the following topics are functional programming-introduction, pattern matching, and some useful algorithms like The Sieve of Eratosthenes and the Fibonacci Series. Advanced topics include folding of lists, lambda calculus, modules, type inference, and type classes. Examples of practical applications, such as an expression evaluator and functions with variable arguments, will provide learners with a sense of how theoretical material might be applied in real-world situations. These detailed lecture notes are intended for readers who would like to go through functional programming in depth - both explanations and exercises.

Functional Programming III

This course note, from the University of Edinburgh and offered online, emphasizes from a very practical point of view how to apply basic functional programming concepts in a graphical environment. Major topics to be covered include recursion, abstraction, higher-order functions, and several different data types-how all these concepts can be used to solve problems is demonstrated. The note introduces theoretical aspects but underlines their practical relevance by showing how these can be put into practice within graphical programming contexts. Learners develop a solid, theoretically based understanding of functional programming principles and get real practical experience applying these principles to graphical applications. This resource takes an integrated approach in the way that it interrelates theory and practice, hence acting as a bridge from concepts of functional programming to real-life practice.
