What is the difference between Go's documentation and specifications for documenting and describing the requirements and specifications of Go programs?

Go's documentation and specifications serve different purposes in documenting and describing Go programs.

Documentation in Go refers to the process of describing how the code works, what it does, and how to use it. It is typically done through comments in the code itself, which can be processed into human-readable documentation using tools like **godoc**. Documentation is intended for programmers who need to understand and use the code, and it provides information such as the purpose and behavior of functions, types, and variables, as well as any usage restrictions, input parameters, and output values.

Specifications, on the other hand, are formal and detailed descriptions of what a program or system is supposed to do, as well as any constraints or requirements it must meet. In Go, specifications are often written using formal methods like Hoare logic, which use mathematical notation to describe program behavior and correctness. Specifications are typically used during software development to verify that a program or system meets its requirements, and they can be used to generate tests and to reason about program behavior.

In summary, while documentation explains how to use and understand code, specifications define what a program is supposed to do and how it should behave.
