## What is ReasonML? (Axel Rauschmayer)

This talk starts by explaining what ReasonML is and how it fits into the current OCaml and JavaScript ecosystems. We’ll also take a look at what is planned for ReasonML’s future.

## Reason for JavaScript Developers (Marius Schulz)

In this talk, we'll explore how to express common JavaScript idioms in Reason. We'll see how to leverage various Reason features like tuples, variants, and pattern matching to write expressive, concise, and type-safe code.

## Making Unreasonable States Impossible (Patrick Stapfer)

Wouldn’t it be great if you could ensure that your application, no matter how much you’ve angered the Software Gods, could not get into weird states? Think of how much easier it would be to document functionality, how much time you’d save on complex test scenarios, and how much more sleep you’d get. That dream can be yours today – and the enigmatic Patrick Stapfer will show you how!

Freelancer and speaker specializing in scalable codebases in JavaScript. Currently working on the OSS project Lagoon (github.com/amazeeio/lagoon), while trying really hard to be a system engineer. First-day user of Flow and static typing evangelist. Most of his spare time is dedicated to the ReasonML community.

## Exploring Reason’s Interop with JavaScript (David Gomes)

In this talk, we explore Bucklescript's Interop System. While the Bucklescript documentation describes the various operators and some of the design decisions, this talk will follow an example-oriented approach where we write bindings for a JavaScript API and create a small Reason demo that leverages this JS API. In the end, we'll also take a look at how the reverse operation can be performed — using a Reason library from JavaScript.
