Want to know if your program is correct before you ship it to the browser? Types can help you know if your code integrates well together. Want more insight into developer intent when reading code? Types can help expose that better. Want more feedback while your coding for a more confident development experience? Typing and compiling your code can help with that too.
Hear the quick pitch on Flow and then see Flow in action in a real-world project environment. This isn't an academic review of all the features of Flow. This is seeing those fundamental features used in the course of creating a real project.
To demonstrate Flow, we make a choose your own adventure game, where the narrative is chosen by the reader over time. It's a silly tale of galactic treachery and loyal friends. We start with an empty directory and end with a small, fully-flowtyped web application.
