Beyond the Basics
Once you've mastered TypeScript fundamentals, these advanced patterns will help you write more robust code.
Discriminated Unions
type Result = \n | { success: true; data: T }\n | { success: false; error: string } This pattern makes it impossible to access data without checking for success first.
Branded Types
Create nominal types that prevent mixing of similar primitive types.
Conditional Types
Types that transform based on conditions, enabling powerful type inference.
