Types can be invaluable when working on a large project, by making refactoring less error-prone, enabling better coordinating between teammates, and improving readability. Reason gives you a powerful, battle-tested type system with cross-file inference, macros, and excellent JavaScript interop. Come learn what differentiates it from added-on type systems like Flow and TypeScript, what it looks like to build React UIs in Reason, and what makes it easy to start into and integrate with your current JavaScript app.

Types can be invaluable when working on a large project, by making refactoring less error-prone, enabling better coordinating between teammates, and improving readability. Reason gives you a powerful, battle-tested type system with cross-file inference, macros, and excellent JavaScript interop. Learn how you can start using Reason right now to bring more safety and maintainability to your React Native codebase, and catch a glimpse of a future where Reason can bypass JavaScript entirely to make your react app truly native.

You may have heard a bit about Reason -- the new initiative out of Facebook to bring JavaScript-flavored OCaml goodness to web developers everywhere -- but what's the big picture?
Reason has a lot of things going for it: fantastic JavaScript interop, a powerful, battle-tested type system with cross-file inference, macros, and plenty of hype. It was started by the folks at Facebook who invented and built React, and already powers a substantial portion of Messenger.com.

We'll go over the basics of Reason, and answer these questions:
- What does it look like to write React UIs with Reason?
- When will Reason be ready for me to use at work?
- What does it look like to incrementally adopt Reason in a JavaScript codebase?
- What tradeoffs has Reason chosen, and how do they compare to other languages?

Type Systems Will Make You a Better JavaScript Developer

State changing over time is a frequent cause of bugs, confusion, and general hair-pulling, and we've developed a number of ways of trying to tame it—observables, concurrent sequential processes, continuation passing style, and async/await. Learn how each of these paradigms work, hear about the advantages and disadvantages of each, and more importantly, discover what they have in common, because they might be more similar than you think.

Paradigms for dealing with asynchrony

Writing fresh code is always more fun than debugging that old stuff you wrote last week, but sometimes you just have to bite the bullet.

- Learn how to use the React Devtools effectively to fix bugs, fight crime, and bring home the bacon.
- Learn best-practices for writing maintainable React components.
- Hear about the tools we use at Khan Academy that assist us in our quest for the ultimate development experience.

Real World React Debugging

Managing client-side state is pretty easy for TodoMVC, but soon after you move beyond that, your app can quickly get brittle, discouraging re-use and significantly complicating maintenance. I will give an overview of a few of the libraries/frameworks that have appeared recently that try to address this problem, show how each of them looks when used in the React context, and then discuss advantages, disadvantages, common patterns, and what we can learn.
