Go Programming: Structs, Methods, and Custom Types

Go is known for its simplicity and efficiency, but transitioning from basic variables to structured data can feel challenging. Understanding how to group related data and define custom behaviors is essential for writing clean, idiomatic Go applications. In this text-based course, you will transition from writing simple scripts to designing robust, reusable data models that form the backbone of modern Go software. By learning to model real-world entities, you will write code that is both easy to read and simple to maintain. What you'll learn: - Define custom structs to represent complex data structures and shapes - Implement methods with value and pointer receivers to manage state safely - Apply modern Go conventions for package visibility and encapsulation - Structure code cleanly to prepare for writing unit tests - Practice modeling geometric entities like rectangles to calculate area and perimeter You will start with core concepts, defining basic structures and understanding memory layout. From there, you will progress to attaching behaviors with methods, managing mutability with pointers, and organizing your code into idiomatic Go patterns. This course is designed for beginning Go developers who have a basic grasp of variables and loops but want to master structured data and object-oriented patterns in Go. No advanced programming experience is required. Start building structured, efficient Go applications today.
