You may have seen generics in C#, Java, or Swift but there are a lot of very useful patterns using generics that rarely get used in an OO context. In this episode, we explore Type Parameters (aka generics) from a functional perspective and how using them can improve the structure of your applications.Episode 21 patrons:Scott SmithJoel McCracken ...…

Lazy evaluation is not normally something you hear programmers discussing but there is a lot of power available if you know how to use it. This episode we'll examine the differences between lazy and strict evaluation and look at use cases for laziness.Episode 20 patrons:Marcus NielsenSteven LoeTed YavuzkurtMichael MeyersSzymon BeczkowskiParl Na ...…

Logan walks us through what his experience has been starting a JavaScript project in a functional style and using the best FP tools he can get in the JavaScript ecosystem.Episode 19 patrons:Nathan SculliLee BeckDavid JoynerNihohitCharles WinebrinnerFP Chat Slack Community: https://fpchat-invite.herokuapp.com…

Monads, the promised land of functional programming. Or at least with all the hype they'd better be! Come join the cast as we demystify this overhyped structure that has become an indispensable part of many functional programmer's toolkits.Episode 18 patrons:PlutonTim BuckleyHuge shout out to Marcus NielsenShow Notes:bind :: m a -> (a -> m b) - ...…

Building on the power of functors we examine a few scenarios where a normal Functor is problematic. Fortunately, there is a closely related structure known as an Applicative Functor that can provide the capabilities to solve a broader range of problems.Episode 17 patrons:Chad WooleyDavid KeathleyAndre CarvalhoShow Notes:Coconut programming lang ...…

Going deeper down the category theory rabbit hole, we explore one of the most common and useful abstractions in the functional programming world. You're likely already familiar with Functors but just didn't know it yet.Episode 16 patrons:Chris KrychoTyler HarperGeorge WebsterShow Notes:Functor map :: (a -> b) -> f a -> f bBifunctor bimap :: (a ...…

Join us as we discuss the FP community. FP has a reputation as harsh and impenetrable but is that really the case? What can you do to make FP a more inviting place?Episode 15 patrons:Chris LopesGabe JohnsonRandy ShepherdNoel WaghornCorrection: I incorrectly stated that one of the Recurse Center Social rules was “No Feigned Ignorance” it is actu ...…

The kind of type system a functional language uses has a large impact on the way you use that language. In this episode we discuss the tradeoffs involved in using a static or dynamic language.Our patreon sponsors this month:Javier TroconisAndrew NewmanDerek MorrOlov JohanssonShow Notes:Philip Wadler Talk: https://www.infoq.com/presentations/cat ...…

Algebraic Data Types (ADTs) are one of the most distinguishing features of statically typed functional languages. Come learn why they exist, how you can use them, and how they change your design.

Into the icy maw of category theory starting with Monoids! In reality we find out it's not actually all that scary and there are some really fantastic things that we gain by understanding these basic categorical concepts.We now have a twitter account!

Partial application and currying are a feature that is often mysterious to the uninitiated. Why do functional programmers care about such a seemingly useless thing? Partial application is an important part of the "FP toolkit" and we'll why and provide use cases for the importance of having partial application.Simple made easy - https://www.info ...…

Abstraction takes on a different meaning amongst functional programmers. This episode we dig into how parametric polymorphism is an essential tool in developing well behaved abstractions that transcend simply being a solution to your individual problem.John Degoes polymorphism posthttp://degoes.net/articles/insufficiently-polymorphicWhen x, y, ...…

Oh category theory, bastion of strange and wonderful terminology, (some might say terrible and inaccessible). Love it or hate it, you're likely to run into some terms from category theory if you spend enough time in FP land. In this episode we'll tackle some of the terms that make up the 'ism family of terms, morphism, endomorphism, isomorphism ...…

Recursion, that infinite spiral of self referentiality. In this episode we break down the ideas behind recursion, and more importantly when and where you might want to use recursion.

To write a program is to deal with uncertainty. Sometimes it feels like there's nothing we can count on and null (or undefined) is as pervasive as any other construct in our languages. However this does not have to be! LambdaCast dives into the thorny problem of null, and more broadly the potential for values not to exist and offers up some alt ...…

This time we tackle the thorny issue of how you get anything done when you're not allowed to change anything. If the idea of immutability seems strange or even impossible, then we've got you covered.

This episode we discuss the ins and outs of higher-order functions. If you've never heard of them don't fear they're not as scary as they sound, in fact you're probably already using them!

This time around we'll be talking over the core benefits of FP and why you might want to consider its use in your projects.Tell us what you think at contact@lambdacast.comShow Notes:https://www.destroyallsoftware.com/talks/boundarieshttp://blog.ploeh.dk/2015/08/17/when-x-y-and-z-are-great-variable-names/…
