json

json ： javascript object notation。一种轻量级的数据交换格式，与xml各有千秋。javascript是它的主战场。

 

JSON is built on two structures:

• A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
• An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.

So，It is very easy to know to learn, but how to use it well is a long term progress.
