TypeScript Gymnastics: Why Are They So Powerful for You?
summary
TypeScript techniques get named and shown with working code: a parseUrlParams type that extracts route params at compile time powers a navigate(url, params) example that errors if required params are missing, template literal and infer-based RGB and returnType extraction demonstrate exact-string validation and return/parameter inference, mapped and recursive types build a getByKey that yields nested object paths and a tiny type-safe query builder; result improves IDE hints and catches mismatches but demands substantial type complexity and maintenance time.
