TypeScript Fundamentals, Part 1: Describing Your Data

The TypeScript Fundamentals series provides a comprehensive learning path across three parts. Part 1 focuses on Describing Your Data using interfaces, type aliases, unions, and tuples. Part 2 emphasizes Writing Safer Code by exploring inference, strict mode, unknown, and narrowing to effectively catch bugs. Part 3 covers Reusable Types, including generics, utility types, and enums versus literal unions. Each section operates independently, allowing developers to read them sequentially or jump to specific technical needs.
