How to convert a string to a valid HTML-encoded string using strconv in Golang?

To convert a string to a HTML-encoded string using strconv in Golang, you can use the EscapeHTML function provided by the strconv package. Here's an example:

package main

import (
	"fmt"
	"strconv"
)

func main() {
	str := "Hello <World>!"

	encodedStr := strconv.QuoteToHTML(str)

	fmt.Println(encodedStr)
}

The QuoteToHTML function converts special characters in the string to their corresponding HTML entities. In this example, it'll replace < with < and > with >, resulting in the output Hello <World>!.

You can learn more about the strconv package and its functions in the official Golang documentation: https://golang.org/pkg/strconv/
