What problem does it solve?

Teaches how to write custom type guards with type predicates and use built-in type narrowing in TypeScript.

Core Features & Use Cases

  • Custom type predicates: create conditions that narrow types.
  • Validation patterns: use type guards with runtime data.
  • Use Case: guard API responses before accessing properties.

Quick Start

Implement a simple isUser guard and use it to safely access user.name.
