jQuery getJSON() Method
In this article, we will learn about the getJSON() method in jQuery, along with understanding their implementation through the example. jQuery is an open-source JavaScript library that simplifies the interactions between an HTML/CSS document, It is widely famous for its philosophy of “Write less, do more”.
The getJSON() method in jQuery fetches JSON-encoded data from the server using a GET HTTP request.
Syntax:
$(selector).getJSON(url,data,success(data,status,xhr))

- url: It is a required parameter. It is used to specify the URL in the form of a string to which the request is sent
- data: It is an optional parameter that specifies data that will be sent to the server.
- callback: It is also an optional parameter that runs when the request succeeds.
Return Value: It returns XMLHttpRequest object.
Please refer to the jQuery Tutorial and jQuery Examples articles for further details.

employee.json file:
{
“name”: “Tony Stark”,
