I also see that I previously wrote in PHP. Please tell me, how was the transition from PHP to Go? Did you take any courses or how did you learn the language?

Switching from PHP to Go usually begins with studying the basic syntax and features of the Go language, such as strict typing, working with goroutines and channels for concurrency, as well as the standard library. I used official documentation and online courses, for example, "A Tour of Go" and courses on the Udemy platform.

Practice was key: rewriting small parts of existing PHP applications in Go to understand differences in error handling, data structures, and code organization.

An example of a simple HTTP server in Go:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, Go!")
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

This approach helped quickly adapt and understand the advantages of Go, especially in multi-threaded and high-load applications.
