🗣️ Sophie Collard: Lessons learnt from a year of building UIs with Elm

Elm describes itself as a "delightful language for reliable web applications" and promises great performance, fearless refactoring and no runtime exceptions. A year ago, frustrated with my limited but already painful experiences with React and Vue, I did what any sane developer would. After spending all of 20 minutes playing with in-browser tutorials, I opted to use Elm as the main language for my next project.

Twelve months and 10k LOC later, I have no regrets whatsoever. But I did find myself going down the wrong path a few times, often when trying to port over concepts from other languages and frameworks. In this talk, I will share what I've learnt about structuring large Elm projects, managing communication between components, JavaScript interop, and a few issues I hope future releases of Elm will address.

🗣️ Nicolas Rinaudo: The debatably Free monad
Free is something I've wanted to understand for quite a while, but could never quite figure it out. I’d essentially given up on it until a friend of mine, known to be particularly fond of pithy statements, told me Free is merely the defunctionalisation of Monad in its most uncomfortable configuration. He didn’t add what’s the problem? but it was clearly implied.

The odd thing though is that after playing with this for a bit, it turned out to be exactly what I needed to hear to get me unstuck.

This talk is my slightly expanded version of that statement, and should hopefully understand what Free is, what purpose it serves and where it came from.

Nicolas Rinaudo
Nicolas writes code for JPMorgan, where we use Scala to make some very complicated things seem very simple.

After too many years as a Java programmer and a thankfully brief stint in marketing, Nicolas discovered Functional Programming through Scala and fell in love. Since then, he's made it his mission to learn and explain the scary bits, by focusing on practical applications.

Nicolas is also the author and sole maintainer of a few useful OSS libraries, such as kantan.csv.
