Type Safety 🛡️

Intro to Type Safety

👨‍💼 Welcome to the Type Safety workshop! This is where TypeScript becomes meaningfully different from JavaScript.

In this workshop, we'll explore how to make illegal states unrepresentable. That means designing types so that invalid data simply cannot exist in your program.

We'll cover:

Type Aliases - Naming and reusing complex types
Union Types - Modeling multiple possibilities
Literal Types - Working with exact values
Intersection Types - Combining behaviors
Any vs Unknown - Escape hatches and safe refinement
Generics - Creating reusable type-safe functions and types
Interfaces - Defining object shapes with contracts
Enums - Using named constants and comparing enums with unions

This workshop transforms how you think about types. Instead of types being an afterthought, they become a design tool for writing correct code.

By the end of this workshop, you'll be able to:

Create reusable type aliases and interfaces
Use literal types for exact value constraints
Model complex domains with union and intersection types
Handle unknown data safely
Create flexible, reusable code with generics
Design types that prevent bugs by construction
Choose between enums and union types

Let's make your types work for you! 🔒
