Very basic design in functional programming languages

Więcej informacji o tym wydarzeniu dostępne jest w języku angielskim: Hi guys! After an amazing meetup last week we're ready for more. Both Tomek and Denys said they are interested in presenting a talk in November. Please message me directly with a talk title and possible dates. If anyone alse has any ideas, please share them! We can schedule more than one in November or December if it turns out there are more suitable dates. So, the first slot has been taken:) Tomasz Kowal submitted this awesome presentation so let's all see what he has to say. If Denys or anyone else has more ideas, please message me directly, we'll set an additional date. Functional programming languages promise to be easier to test and easier to debug. However, when learning the functional way we often try to translate our current techniques to another language. This is usually not easy and the end result is far from those promises we've heard. Early frustrations might even discourage from further learning. In this talk I will show two very simple patterns:

• designing code around single data structure
• dealing with impure parts of program like DBs, external services or IO

This should give beginners jump start for their first toy projects and further exploration.
