As you may know, JSON is used extensively in modern web development, particularly to communicate data between servers and clients in Rich Internet Applications, or Web 2.0 applications. JSON is commonly the preferred choice for data interchange between clients and servers which use a Respresentational State Transfer (REST) based architecture.

JSON is often the preferred choice because it is a fat free alternative to XML. Although we use XML all the time, we fully recognise that it be both complex to work with and inefficient to generate and parse. JSON, on the other hand, is both simple and fast.

Jyson is written in pure java, and should be highly performant. So, if you’re using jython and JSON, we recommend you check out jyson.
