Introduction to Dependent Types and Type-Level Scala

Traditional types prevent basic bugs, but what if your type system could prove the correctness of your code at compile time? Dependent types allow you to parameterize types with values, bridging the gap between logic and programming. This text-based course guides you through the foundational concepts of dependent types and type-level programming using modern Scala. You will learn how to move runtime checks to compile-time guarantees, ensuring your software is correct by construction. What you'll learn: Understand the theoretical foundations of dependent types and the Curry-Howard isomorphism; Implement dependent function types and path-dependent types in modern Scala; Design type-safe data structures like generalized algebraic data types and sized vectors; Apply implicit resolution and type-level programming techniques to solve complex domain problems; Write compile-time assertions and proofs using advanced language features. We begin with the core mathematical and logical concepts behind advanced type systems. From there, you will read through step-by-step code explanations and conceptual breakdowns, gradually building up to sophisticated type-level patterns. This course is designed for developers who have a basic familiarity with functional programming and want to explore the cutting edge of type safety.
