TypeScript Intermediates - Type Generics

A practical introduction to TypeScript type generics, explaining why they're needed and how to use them. Covers the limitations of alternatives like unions, function overloading, and `any`, then demonstrates how generics solve the problem of preserving type information across inputs and outputs. Includes real-world examples with functions, interfaces, classes, and type definitions, plus how to restrict generic types using `extends` for polymorphic functions.
