AJAX - Low Level Interface

jQuery is a popular JavaScript library that provides a simple and convenient way to perform Ajax (Asynchronous JavaScript and XML) requests. Ajax allows you to send and receive data from the server without reloading the entire page. The low-level interface for Ajax in jQuery consists of the following methods:

jQuery.ajax() - This method is the foundation of all Ajax requests in jQuery. It is used to send an HTTP request to the server and receive a response. You can specify various options such as the URL, type of request (GET or POST), data to send, and so on.

jQuery.get() - This method is a shorthand for making a GET request. It is used to fetch data from the server and does not require any data to be sent.

jQuery.post() - This method is a shorthand for making a POST request. It is used to submit data to the server.

jQuery.load() - This method is used to load HTML content from the server and insert it into the current page.

jQuery.getJSON() - This method is used to fetch JSON data from the server.

jQuery.getScript() - This method is used to fetch and execute a JavaScript file from the server.

These methods all use the jQuery.ajax() method under the hood to perform the Ajax request. However, they provide a simpler and more convenient interface for common use cases.
