What problem does it solve?
Conditional types in TypeScript distribute over unions by default, often producing surprising results. This skill explains how to control distribution so you can prevent it when undesired and enable it when needed.
Core Features & Use Cases
- Understand distributive behavior of conditional types over unions.
- Prevent distribution using one-tuple wrappers; force distribution with bare conditions.
- Handle edge cases involving boolean and never, including recursive types that may misbehave.
Quick Start
Demonstrate how to prevent distribution over unions by wrapping the type in a one-tuple in a TypeScript example.
