What is the difference between Go's structs and classes for defining and using structured types and objects in Go programs?
Go does not have classes in the traditional object-oriented programming sense. Instead, Go uses structs to define structured types. Structs are similar to classes in that they can have fields that hold data, but they do not have the same level of functionality as classes.
In Go, structs are used to group related data together and to define methods that can be called on that data. However, unlike classes, structs do not have inheritance or polymorphism. Instead, Go uses interfaces for defining and implementing behaviors that can be shared across different types.
One of the main differences between Go's structs and classes is that structs are value types while classes are reference types. This means that when a struct is passed to a function or assigned to a variable, a copy of the struct is made, while with classes, a reference to the object is passed. This can have implications for memory management and performance.
