JSON File Reading and Decoding

fetch('https://jsonplaceholder.typicode.com/users/1')
    .then(response => response.json())
    .then(data => {
        console.log(data);
        console.log("الاسم:", data.name);
    })
    .catch(error => {
        console.error("حدث خطأ:", error);
    });

في هذا المثال، نستخدم fetch() لطلب بيانات من API، ثم نستخدم response.json() لتحويل الاستجابة إلى كائن JSON يمكننا التعامل معه.

In this guide, we'll explore how AJAX works, the basics of making AJAX requests using vanilla JavaScript, and some real-world examples to help you implement AJAX in your own projects.

• Basic knowledge of HTML, CSS, and JavaScript.
• Familiarity with JSON (JavaScript Object Notation) as a format for exchanging data.

Add the updateBook function to main.go:

func updateBook(w http.ResponseWriter, r *http.Request) {
	w.Header().Set("Content-Type", "application/json")
	params := mux.Vars(r)
	for index, item := range books {
		if item.ID == params["id"] {
			books = append(books[:index], books[index+1:]...)
			var book Book
			_ = json.NewDecoder(r.Body).Decode(&book)
			book.ID = params["id"]
			books = append(books, book)
			json.NewEncoder(w).Encode(book)
			return
		}
	}
	json.NewEncoder(w).Encode(books)
}
