JSONP (JSON with Padding) is a technique for requesting data from a remote server and receiving the response in JSON format, even if the server and client are on different domains. This is possible because JSONP uses the <script> tag to load the data, which is not subject to the same-origin policy as other types of requests.
To make a JSONP request, the client creates a <script> tag with the src attribute set to the URL of the remote server. The URL must include a callback function name, which is the name of a function that the client will define to handle the response.
When the browser encounters the <script> tag, it will download the script from the remote server and execute it. The script will then call the callback function, passing in the JSON data as a parameter.
The client can then parse the JSON data and use it in its application.
The following example shows a simple JSONP request:
<script src="https://example.com/jsonp?callback=myCallback"></script> The myCallback() function will be defined in the client's JavaScript code. When the browser downloads and executes the script from the remote server, it will call the myCallback() function, passing in the JSON data as a parameter.
function myCallback(data) { } JSONP has several benefits over other techniques for cross-domain data retrieval, such as CORS:
- JSONP is simple to implement. All that is required is to create a
<script>tag and define a callback function. - JSONP is supported by all major browsers.
- JSONP is relatively fast.
JSONP also has some drawbacks:
- JSONP is not as secure as CORS, as it is vulnerable to cross-site scripting (XSS) attacks.
- JSONP is not as flexible as CORS, as it can only be used to retrieve data from servers that support JSONP.
JSONP is commonly used in the following situations:
- To retrieve data from a remote server that is on a different domain than the client application.
- To retrieve data from a server that does not support CORS.
- To retrieve data from a server that is located in a different country.
JSONP is a simple and effective technique for requesting data from a remote server and receiving the response in JSON format, even if the server and client are on different domains. It is commonly used in web applications, mobile applications, and other types of software.

Enter JSONP. When you make your request to a server that is JSONP enabled, you pass a special parameter that tells the server a little bit about your page. That way, the server is able to nicely wrap up its response in a way that your page can handle. For example, say the server expects a parameter called callback to enable its JSONP , .

JSONP VS JSON. The best way to describe JSONP vs JSON is that JSON is raw data, and JSONP is JavaScript with the data embedded into it. JSON (JavaScript Object Notation) is raw data that can be parsed and then used in JavaScript, whilst JSONP (JSON with Padding) is data that comes with a callback function. .

JSONP, an acronym for JSON with Padding, was conceived as a technique to circumvent the constraints imposed by the Same-Origin Policy. At its core, JSONP uses HTML script tags to enable cross-origin data requests. 3.2. The Art of Overcoming SOP Restrictions. JSONP operates by exploiting a gap in the Same-Origin Policy (SOP). .

JSONP has always been one of the most poorly explained concepts in all of web development. This is likely due to its confusing name and overall sketchy background. Prior to the adoption of the Cross-Origin Resource Sharing (CORS) standard, JSONP was the only option to get a JSON response from a server of a different origin. .
