Read JSON Data from a File

const jsonString = '{"name":"أحمد","age":30,"isMarried":false,"children":["سارة","علي"]}';

const person = JSON.parse(jsonString);
console.log(person.name);  // أحمد
console.log(person.age);   // 30

غالبًا ما يتم استخدام JSON في التفاعل مع واجهات برمجية (APIs) لجلب البيانات من الخادم. يمكنك استخدام fetch() في JavaScript لطلب بيانات JSON من API.

In this guide, we've covered the basics of AJAX, focusing on how to make requests using both XMLHttpRequest and the modern Fetch API. AJAX allows you to create more dynamic and responsive web applications by enabling seamless communication between the client and server without reloading the entire page.

By mastering AJAX with JavaScript, you'll be able to implement interactive features like real-time updates, live data fetching, and much more in your web applications.

func getBook(w http.ResponseWriter, r *http.Request) {
	w.Header().Set("Content-Type", "application/json")
	params := mux.Vars(r)
	for _, item := range books {
		if item.ID == params["id"] {
			json.NewEncoder(w).Encode(item)
			return
		}
	}
	json.NewEncoder(w).Encode(&Book{})
}

Add the createBook function to main.go:
