TypeScript conditional types let you build types based on conditions, enabling sophisticated type logic for robust applications. They act like type-level if statements, checking relationships between types to determine the resulting structure dynamically.

TypeScript generics allow you to create reusable components with type flexibility. By defining generic parameters, you can write functions and classes that maintain strict type safety across various data structures without duplicating code.

Mapped types in TypeScript work by iterating over an existing type's properties to transform them. This mechanism allows you to systematically modify property modifiers or value types, creating new derived structures for type-safe applications.

TypeScript template literal types are string-based types that enable pattern matching and string transformations. You need them when building robust applications that require strict string format validation or dynamic string concatenation at the type level.

Yes, you need knowledge of TypeScript fundamentals before using advanced types. Mastering the advanced type system requires a solid understanding of basic types and interfaces to effectively implement generics, conditional types, and utility types.
