What is ajax and jquery and also write a program to combine it and explain every line with neat explanation?

Ajax (Asynchronous JavaScript and XML) is a set of web used to create asynchronous web applications. It allows web pages to be updated asynchronously by exchanging small amounts of data with the server, instead reloading the entire page. This results in a smoother and more dynamic user experience.

jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, and animation much simpler with an easy-to-use API that works across a multitude of browsers.

Now, let's combine Ajax and jQuery to create a program that fetches and displays data from a server using Ajax and jQuery:

<!DOCTYPE html>
<html>
<head>
 <title>Ajax and jQuery Example</title>
  <script src="https://code.jquery.com/jquery3.6.0.min.js"></script>
  <>
    $(document).ready(function(){
      $("#fetchData").click(function(){
        $.ajax({
          url: "https://api.example/data",
          method: "GET",
          success: function            $("#displayData").text(response);
          },
          error: function(error){
            console.log("Error:", error);
          }
        });
      });
    });
  </script>
</head>
<body>
  <h1jax and jQuery Example</h1>
  <button id="fetch">Fetch Data</button>
  <div id="display"></div>
</body>
</html>

Explanation of the code:

  1. The program includes jQuery library using a script tag.
  2. The jQuery document ready function is used to ensure that the code inside it is executed only after the HTML document is fully loaded.
  3. When the button with the id "fetchData" is, an Ajax request is made using the $.ajax() function.
  4. The URL specifies the endpoint from which data will be fetched.
  5. The method specifies the HTTP method to be used, in this case, GET.
  6. If the request is successful, the is displayed in the element with the id "displayData".
  7. If there an error with the request, an error message is logged to the console.

This program demonstrates a basic use case of combining Ajax and jQuery to fetch and display data asynchronously from a server.
