Overview
What you’ll learn—and how you can apply it
Julia's type system is one of its key features, and enables both flexible programming and fast performance. But, what is a type and how can it optimize your code?
In this lesson, we'll introduce types in Julia, and discuss how to use them effectively in your code. We'll explore Julia’s built-in types as well as show you how to define your own, including defining custom constructor methods. We'll also help you get a feel for various design decisions you'll face, such as when to use mutable vs. immutable types.
This lesson is for you because
You are a relatively new Julia developer looking for a firm foundation in Julia's type system. You want to write code that is high-performance without sacrificing maintainability.
