Thinking Functionally

This series of posts will introduce you to the fundamentals of functional programming – what does it really mean to "program functionally", and how this approach differs from object oriented or imperative programming.

1. Thinking Functionally: Introduction - A look at the basics of functional programming
2. Mathematical functions - The impetus behind functional programming
3. Function Values and Simple Values - Binding not assignment
4. How types work with functions - Understanding the type notation
5. Currying - Breaking multi-parameter functions into smaller one-parameter functions
6. Partial application - Baking-in some of the parameters of a function
7. Function composition - Building new functions from existing ones
8. Combinators - Parsers and more
9. Function signatures - A function signature can give you some idea of what it does
10. What is LINQ really? - LINQ is used for collections right? Yes, but much, much more.
11. Organizing functions - Approaches to organising your application architecture
12. Attaching functions to types - Creating methods the language-ext way
13. Worked example: A stack based calculator - Using combinators to build functionality
