To create a simple HTTP server in Go (Golang), you can use the built-in net/http package. Here's a basic example:

1package main
2
3import (
4    "fmt"
5    "net/http"
6)
7
8func handler(w http.ResponseWriter, r *http.Request) {
9    fmt.Fprintf(w, "Hello, World!")
10}
11
12func main() {
13    http.HandleFunc("/", handler)
14    http.ListenAndServe(":8080", nil)
15}

1package main
2
3import (
4    "fmt"
5    "net/http"
6)
7
8func handler(w http.ResponseWriter, r *http.Request) {
9    fmt.Fprintf(w, "Hello, World!")
10}
11
12func main() {
13    http.HandleFunc("/", handler)
14    http.ListenAndServe(":8080", nil)
15}

Explanation:

• Package Import: We import fmt for formatting and net/http for HTTP server functionalities.
• Handler Function: The handler function writes "Hello, World!" to the response.
• Main Function: We set up the route and start the server on port 8080.

Differences from JavaScript in Backend Development:

• Concurrency: Go has built-in support for concurrency with goroutines, making it easier to handle multiple requests simultaneously compared to JavaScript's event-driven model.
• Static Typing: Go is statically typed, which can help catch errors at compile time, while JavaScript is dynamically typed.
• Performance: Go generally offers better performance for CPU-bound tasks due to its compiled nature.

This simple server is a great starting point for understanding how to build web applications in Go!
