TypeScript - Beyond the Basics
summary
Covers concrete TypeScript techniques: using generics for type-safe collections, combining classes with intersection types and a runtime mixin function that copies prototypes (example creates a billable+programmer object and works with VS Code intellisense), modeling failure as a Union type programmer|lookupFailed and distinguishing cases with type guards, demos run with TS-Jest, and the reminder that type safety exists at compile time only because emitted JavaScript is plain arrays and objects.
