In Go, both methods and functions are fundamental constructs used for code organization and reuse. Although they share similarities, they have distinct characteristics and use cases. Understanding the differences between methods and functions is crucial for writing effective and idiomatic Go code. This guide explores the distinctions between methods and functions, their syntax, and practical examples.

In Go, methods and functions are both essential constructs but serve different purposes. Functions are standalone and not tied to any specific type, making them suitable for general-purpose operations. Methods, on the other hand, are associated with specific types and provide a way to encapsulate behavior and access data related to those types. By understanding these differences, you can effectively organize your Go code, enhance readability, and leverage Go's type system to create more robust and maintainable applications.
