Explain the use of Go's documentation and commenting conventions for documenting and explaining the code and design of Go programs for various stakeholders and users?
Go has built-in support for documentation through its "go doc" command, which generates documentation from code comments. Go uses a special format for documentation called "godoc" that is similar to other documentation formats like Javadoc and Doxygen.
In Go, comments that immediately precede a type, variable, constant, function, or method declaration are considered to be documentation for that entity. These comments can include special tags such as
**@return** to describe the function parameters and return values.
Go also has a convention for writing package-level documentation. Each package should include a file named
**doc.go** that contains package-level documentation. This documentation should include a brief description of the package and its functionality, as well as any important information about how to use the package.
In addition to code comments and package-level documentation, Go also supports the use of external documentation tools, such as the popular "godoc.org" website, which provides a searchable index of Go documentation.
Overall, Go's documentation and commenting conventions are designed to make it easy for developers to understand and use Go code, as well as to facilitate collaboration and code sharing among developers.
