Typescript: Beyond the Type Hype

JavaScript may be lingua franca of the web, however its dynamic type system is often a struggle for tooling to handle and a source for defects in larger projects. TypeScript alleviates this problem by adding type checking. However, there is much more to TypeScript than just the syntactic sugar. 

TypeScript: Beyond the Type Hype delves into advanced types and how they may be used to build and extend your own custom types. After getting a better handle on advanced types, the library io-ts is introduced to allow you to leverage your types as data flows in and out of your application and across I/o boundaries, promoting TypeScript from a compile or transpile time-only concern to a runtime safety net.
