Template Literal Types

Build types from string templates. Perfect for creating type-safe APIs, CSS-in-JS solutions, and domain-specific languages within TypeScript.

Advanced Utility Types

Master built-in utility types and create your own. Learn when to use Pick, Omit, Exclude, Extract, and how to combine them for complex type manipulations.
