What is the rationale for having these two interfaces in the language? What is the point of creating these abstractions? What is the rationale for having these two interfaces in the language? What is the point of creating these abstractions?
Let’s assume we need to implement a function that should copy the content of one file to another. We could create a specific function that would take as input two `*os.Files`. Or, we can choose to create a more generic function using `io.Reader` and `io.Writer` abstractions: Let’s assume we need to implement a function that should copy the content of one file to another.
