What problem does it solve?
Many TypeScript concepts like union, intersection, extends, and never are hard to reason about when thinking in terms of properties. Framing types as sets clarifies which values are allowed and how type relationships work, reducing confusion and errors.
Core Features & Use Cases
- Mental model: Treat types as sets of values to determine subset relationships.
- Practical guidance: Understand why A & B can have more properties than A or B and why A | B has fewer guaranteed properties.
- Use cases: Debug assignability errors, design generic constraints, and reason about conditional types.
Quick Start
Explain the set-theory interpretation of a TypeScript union and intersection example and identify assignability relationships.
