How to join multiple path components into a single path using the path package in Golang?

To join multiple path components into a single path using the path package in Golang, you can use the Join function.

Here's an example:

package main

import (
	"fmt"
	"path"
)

func main() {
	// Define the path components
	dir := "/var"
	subdir := "www"
	filename := "index.html"

	// Join the path components
	fullPath := path.Join(dir, subdir, filename)

	// Print the joined path
	fmt.Println(fullPath)
}

In this example, we have three path components: dir, subdir, and filename. We then use the Join function from the path package to join these components into a single path. The resulting path will be /var/www/index.html.

You can join as many path components as you need by simply passing them as arguments to the Join function. The function takes care of handling any slashes or separators required for a valid path.
