Executing javascript code within a golang environment

Question

Executing javascript code within a golang environment

Is it possible to include JavaScript code within Go code?

package main

import (
    "fmt"
    "net/http"
)
func work(w http.ResponseWriter, r *http.Request){
    fmt.Printf("<script>console.log('javascript working')</script>")

}

func main() {
    http.HandleFunc("/", work)
    http.ListenAndServe(":4000", nil)
}

After running this code in the browser and checking the console window, there doesn't seem to be any output. Is there a way to execute JavaScript within Go code? It seems challenging to use Ajax with Golang.

This is a straightforward piece of JavaScript embedded in Go code:

package main

import (
    "fmt"
    "net/http"
)

func main() {
    hello := "hello yu bn"
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, `<html>
            <head>
            </head>
            <body>
            <h1>Go Timer (ticks every second!)</h1>
            <div id="output"></div>
            <script type="text/javascript">
            console.log("`+hello+`");
            </script>
            </body>
            </html>`)
    })
    http.ListenAndServe(":9000", nil)
}

It's pretty cool! Make sure to check the browser console for any output!
