  • The only major browser that definitely will not support HTML5 is Internet Explorer, but Internet Explorer 9 for desktop is going to support HTML5. Eventually the mobile browser will as well. Saying a browser supports HTML5 does not mean it supports full HTML5 spec right now. It simply means that it supports a portion of the spec and is on track to support it fully.

  • JSONP or "JSON with padding" is a complement to the base JSON data format, a pattern of usage that allows a page to request data from a server in a different domain. As a solution to this problem, JSONP is an alternative to a more recent method called Cross-Origin Resource Sharing . Under the same origin policy , a web page served from cannot normally connect to or communicate with a server other than An exception is the HTML <script> element. Taking advantage of the open policy for <script> elements, some pages use them to retrieve Javascript code that operates on dynamically-generated JSON-formatted data from other origins. This usage pattern is known as JSONP. Requests for JSONP retrieve not JSON, but arbitrary JavaScript code. They are evaluated by the JavaScript interpreter, not parsed by a JSON parser.
