Dojo is nice toolkit which completelty makes us not to think of writing cross-platform script, all these environmental botherations are taken care by Dojo. We can download, this javascript and place it in our webapplication to use it, or else we can use any of the Content Delivery Network to refer from our web application.
JSON
JavaScript Object Notation is lightweight data interchange format. Usually, we get use SOAP message to send/receive platform agnostic messages, Whereas we have to use any of the XML parsing technique DOM, SAX, JAXB and StAX. And moreover, the message size will be increased to hold tag names meaningful. If we have client-server application where our software runs in client environment which knows what data is getting transmitted between server and client then JSON is the best option.
JSON provides facility to convert normal string to object and Object to normal string in most of the softwares - JAVA, ASP, PHP and etc.,
JSON can represent four primitive types (strings, numbers, booleans, and null) and two structured types (objects and arrays).Read more RFC 4627
