Generics were one of the most anticipated features added to Go, and this course helps you use them effectively without overcomplicating your code. You’ll start with an introduction to type parameters, constraints, and type inference, and how they integrate smoothly into Go’s existing type system.
You’ll then explore real-world use cases where generics shine:
-
Implementing type-safe data structures like stacks, queues, and linked lists.
-
Writing reusable utility functions (e.g.,
Map,Filter,Reduce) without relying oninterface{}. -
Creating libraries that work seamlessly with multiple types while avoiding code duplication.
At the same time, you’ll learn where generics should not be used—for example, when plain interfaces or concrete types keep code more readable. You’ll also benchmark generic implementations against non-generic ones to understand performance trade-offs.
The course emphasizes idiomatic Go design, so you’ll finish with a clear understanding of how to integrate generics responsibly into real-world projects. You’ll even build a small package of generic utilities and publish it as a reusable Go module to see the entire workflow in practice.
