Ed Charbeneau** :** Hello and welcome to Eat Sleep Code, the official Telerik podcast. I'm your host, Ed Charbeneau, and with me today is Dave Fancher.

Dave Fancher** :** Hello!

EC: And today Dave and I will be talking about functional programming in .NET. Dave is author of, The book of F#, from No Starch Press and a Microsoft MVP for .NET and also the owner of Achiiv Solutions. Dave is a Pluralsight author, and he's done a course called, "Building F# Type Providers" and he's working on a new course about functional programming with C#. So Dave what is functional programming?

DF: So ask ten different programmers what functional programming is, and you'll likely get ten different answers. But in general, they tend to boil down to three main characteristics. The first one is that functional programming is about controlling side effects, side effects are anything that changes the external state of the system. It could be as benign as writing to a log file, or it could be more nefarious like changing some shared data across the system. Under functional programming, we wanna control that as much as possible, also under functional programming, we tend to focus on expressions rather than statements, so C# tends to be statement-based. There are some expressions in there, but for the most part it's statement based, your if statements, your using statements, and so on, versus a functional language tends to be focused on expressions, rather than executing something for its effect we wanna execute something for its result. And then finally, functional programming is really centered on the idea of mathematical functions. And so functional languages want to treat functions as data. So you can pass around functions just as you would an integer or a string and that gives way to higher order functions, which is where most of the power of functional programming comes from.

EC: So you're controlling the mutability of the data in the application.

"Nominees" by Zack Sulsky

To run education for our nation wouldn’t it be prudent
To find someone who’d ever been a teacher, or hell, a student?
And is it wise for oil guys with ties from here to Russia
To now decide how we reply to every global dust up?

I’m positive I’m just being negative
And negative’s no way to live
But honestly I can't see the comedy
In the oddity of all these nominees
Cause honestly I’m scared of what it means

The new attorney general is generally racist
He might strike down voting rights on some divisive basis
The protector of our environment should not reject the science
Consensus isn’t senseless and the risk outweighs the bias

I’m positive I’m just being negative
And negative’s no way to live
But honestly I can't see the comedy
In the oddity of all these nominees
Cause honestly I’m scared of what it means

The enemy of energy is suddenly oh so polite
And nuclear's no joke, you’d hope that he’d at least pronounce it right
I don’t mean to cast aspersions but what do surgeons know of urban needs
And a ranking banker regulating banks sounds like it’s ripe for greed

I’m positive I’m just being negative
And negative’s no way to live
But honestly I can't see the comedy
In the oddity of all these nominees
Cause honestly I’m scared of what it means

So don’t confirm them, congresspeople, please
