🔍 Overview
Chapter 10 explores how generics extend beyond data structures into algorithms and iteration. It shows how to write flexible, reusable logic that works across many types while maintaining type safety.
💡 Key Concepts
- Generic Algorithms: Demonstrates how to write functions like `map`, `filter`, and `reduce` using generics.
- Type-Safe Iteration: Explains how iterators and iterable protocols work in TypeScript.
- Custom Iterators: Shows how to define your own iterator logic using `Symbol.iterator`.
- Generator Functions: Introduces `function*` syntax for building lazy sequences and complex iteration flows.
- Generic Constraints: Covers how to restrict algorithm inputs to ensure correctness and compatibility.
- Reusable Patterns: Encourages abstraction of common logic into generic utilities for broader reuse.
🧭 Takeaway
Generic algorithms and iterators empower developers to write expressive, reusable logic that adapts to many types. By mastering these patterns, TypeScript becomes a powerful tool for building scalable and elegant solutions.
