XML is a widely used language that was once the de facto standard for data interchange between applications. Since the advent of JSON, however, it has lost the advantage to the more simple nature of JSON. Nevertheless, XML is still used by applications and SOAP based web services
JSON pronounced as "Jason" is the de facto standard for data interchange on the web these days. It is a simple format that is easier to comprehend than XML. It also has less size than XML because of no closing tags. Interacting with JSON from JavaScript is extremely seamless.
