About this deck

Discover how TypeScript enables precise type modeling through union and literal types. This deck teaches you how to represent values that can take multiple forms and how to restrict variables to specific allowed values.

Through concise explanations and interactive quiz cards, you’ll practice identifying and defining unions such as string | number and literal types like 'success' | 'error'. These concepts are fundamental for building reliable APIs, enforcing valid states, and improving code readability. Practice directly in your browser and gain confidence in expressing complex logic with TypeScript’s type system.
