AJAX - Shorthand Methods
In addition to the low-level Ajax interface, jQuery also provides several shorthand methods that simplify common Ajax tasks. These methods are:
$.get() - This method is used to fetch data from the server using a GET request. It takes a URL as its first argument and an optional data object as its second argument. It returns a Promise object that can be used to handle the response.
$.post() - This method is used to submit data to the server using a POST request. It takes a URL as its first argument, a data object as its second argument, and an optional callback function as its third argument. It returns a Promise object that can be used to handle the response.
$.getJSON() - This method is used to fetch JSON data from the server using a GET request. It takes a URL as its first argument and an optional data object as its second argument. It returns a Promise object that can be used to handle the response.
$.getScript() - This method is used to fetch and execute a JavaScript file from the server using a GET request. It takes a URL as its first argument and an optional callback function as its second argument. It returns a Promise object that can be used to handle the response.
$.load() - This method is used to load HTML content from the server and insert it into the current page. It takes a URL as its first argument and an optional data object as its second argument. It returns the jQuery object for chaining.
These methods are shorthand for the corresponding low-level Ajax methods ($.ajax(), $.ajax({type: "POST"}), $.ajax({dataType: "json"}), $.ajax({dataType: "script"}), and $.ajax({dataType: "html"}) respectively). They provide a simpler and more concise syntax for common Ajax tasks.
