Reading Diary: Real World Functional Programming - Day 2

A reading diary is my way to discuss with myself what I think about the book as I read it. It probably has errors of different kinds.

Some notes on the remaining of Chapter 1

• F# intro, how its mostly functional but supports some OO features

• How C# incorporates functional ideas.

• Reading about declarative programming, these made no sense

  • Definition of declarative programming style. Logic without the details… mmm ok lets see how this goes

  • Functional means not only we can add new commands but also new structures

• Code, finally a code example came about and it was all cleared up

• Concurrency friendly application design, I was expecting the how but I got a birds eye. Patience

• The section on how functional style shapes your code is cool, as it details how your code will (hopefully) slowly change. It highlights

  • the fact that OO design is still useful,

  • it helps simplifying some patterns

  • make the code more readable (this I’m not so sure about, I’ve read code from people who started learning functional programming and on my view the code was less readable and harder to follow, particularly on tests)

• Section 1.4 is all example based. Not mad about the fact they used WPF for one of them(not a fan), but no biggie, it gets the point across anyway . The author obviously wanted the reader to understand what declarative and imperative means and understand the difference

• I can start to see how this style of programming could be really beneficial

• Got as far as the recursion samples with C# (2.2.3)

That’s all for today. It’s been hard to find time to read up on this.
