What are the similarities and differences between Golang function documentation and documentation in other programming languages?

Function documentation comparison: Similar to other languages, function documentation is implemented in Go language through comments, but the difference is that Go uses comments starting with three slashes (///), while other languages ​​use specific symbols to surround comments. Go encourages the use of the Markdown format, which provides features such as code blocks, lists, and links, while other languages ​​use specific markup formats. Although the function documentation of the Go language is concise and clear and supports multiple languages, it lacks specification verification and is prone to manual update inconsistencies.

Go function documentation: comparison with other languages

In the Go language, function documentation is implemented through comments. Compared with other programming languages, this form of documentation has the following similarities and differences:

Similarities:

• ##All languages ​​provide function documentation:All major programming languages ​​allow developers to provide documentation for functions through comments or special tags.
• Similar purposes: The purpose of function documentation is similar in all languages, which is to explain the purpose, behavior and use of functions.

Differences:

Comment style:

Go language: use three backslashes Inline comments starting with a dash (///).
• Other languages ​​(such as Java, Python): Use specific symbols (such as
• /** and """) to surround multi-line comments.

Document format:

Go language: Encourage the use of Markdown format, support code blocks, lists and links
• Other languages: Usually use specific. Format, such as JavaDoc or Doxygen comments, where each element consists of tags

##Practical example:

The following is an example of documentation for a Go function. :

// MyFunction ...
//
// 输入：
// - param1 参数1 的描述
// - param2 参数2 的描述
//
// 返回值：
// - result1 返回值1 的描述
//
// 用途：
// 这个函数用于...
func MyFunction(param1 int, param2 string) (result1 int, result2 string) {
    // 函数体
}

Advantages:

##Concise and clear:

Markdown format is easy to read and understand.
• Multi-language support:
Markdown is widely supported across different operating systems and editors
Disadvantages:

# #Lack of validation:

Function documentation in the Go language does not enforce any format or content specifications

• Manual updates: When a function changes, the documentation must be manually updated, which is easy to happen. Inconsistent.
