Type checking JavaScript with Flow

JavaScript is a dynamic language, and there's nothing wrong with that. It allows quick iteration and lowers barriers. However, sometimes some compile-time type checking is just what you need to keep your code in line and give yourself the confidence to build bigger and faster. Flow gives the best of both worlds. You can have normal JavaScript but you can also add types where they're helpful, and it adds zero cost at runtime. In this talk I'll show Flow as it applies to a Redux & React codebase.
