What is the difference between AJAX calls and AJAX objects?

AJAX (Asynchronous JavaScript and XML) is a technique that allows web pages to update their content dynamically, without requiring a full page reload.

AJAX calls refer to the process of making a request to a server using JavaScript, in order to retrieve or send data. This is typically done using the XMLHttpRequest or the Fetch API, which are built-in JavaScript objects that allow you to make HTTP requests.

An AJAX call typically consists of the following steps:

1. Creating an instance of the XMLHttpRequest or Fetch API object
2. Configuring the request by setting the HTTP method, URL, and any other necessary request headers
3. Sending the request to the server
4. Processing the response from the server, which can include parsing the response data and updating the page's content

On the other hand, AJAX objects are JavaScript objects that are used to make AJAX calls. The XMLHttpRequest and Fetch API are examples of AJAX objects. These objects provide the functionality to make a request to a server and process the response, allowing you to retrieve or send data asynchronously.

To summarise, AJAX calls are the process of making a request to a server to retrieve or send data, while AJAX objects are the JavaScript objects that are used to make these requests.
