How do I handle paths portable across OSes in Go?

In Go, handling file system paths in a way that is portable across different operating systems can be achieved using the "path/filepath" package. This package provides functions that take care of the differences in file separators and other related issues. By using the appropriate functions, you can construct file paths that will work whether you are on Windows, Linux, or macOS.

package main

import (
    "fmt"
    "path/filepath"
)

func main() {
    // Example of joining paths in a cross-platform manner
    homeDir := "user"
    fileName := "document.txt"
    fullPath := filepath.Join(homeDir, "documents", fileName)

    // Output the constructed path
    fmt.Println("The full file path is:", fullPath)
}
