What is the difference between Go's named and anonymous functions?

In Go, a named function is a function that is declared with a name and can be called by that name in the same package or in other packages that import it. An anonymous function, also known as a lambda function, is a function that is declared without a name and can be assigned to a variable or passed as an argument to another function.

Named functions are useful for organizing and encapsulating code logic into reusable units that can be called from other parts of the program. They can also be used as methods on custom types to implement behavior specific to that type.

Anonymous functions are useful for providing functionality that is specific to a certain context, without cluttering the namespace with a new function name. They are often used as callbacks or as parameters to higher-order functions.

In general, named functions are more versatile and can be used in a wider range of scenarios, while anonymous functions are more concise and provide a way to define behavior in a more functional style.
