While AJAX originally stood for "Asynchronous JavaScript and XML," JSON has become the most commonly used data format over XML.

When a user performs an action on the page, like clicking a button, JavaScript can send a request to a server, receive data, and update the page content without reloading the whole page.

Add the createBook function to main.go:

func createBook(w http.ResponseWriter, r *http.Request) {
	w.Header().Set("Content-Type", "application/json")
	var book Book
	_ = json.NewDecoder(r.Body).Decode(&book)
	book.ID = "b" + string(len(books)+1) // Simple ID generation
	books = append(books, book)
	json.NewEncoder(w).Encode(book)
}

In this tutorial, we will walk through the process of building a simple REST API using Flask, a lightweight and flexible web framework for Python. We will cover setting up the Flask environment, creating endpoints, handling HTTP requests, and returning JSON responses.

A REST API (Representational State Transfer Application Programming Interface) is a set of rules that allow applications to communicate with each other over the web. REST APIs are commonly used to build web services and are known for their simplicity and scalability. They rely on stateless communication, typically using HTTP methods like GET, POST, PUT, DELETE, etc.
