Description
Comments are lines of text ignored by the compiler. They are used to explain code logic. Go supports C-style comments: single-line (`//`) and multi-line (`/* ... */`).
Pros & Cons
✅ Pros
- Documentation: Essential for code maintainability.
- Godoc: Special comments generate automatic documentation.
❌ Cons
- None.
When to Use
Documenting public functions and complex logic.
Example
Using formatting for Godoc.
// Package main defines the entry point.
package main
import "fmt"
// main is the primary function.
func main() {
// This prints text
fmt.Println("Comments example")
}Best Practices
Write comments for all exported (capitalized) functions. Start the comment with the function name.
