本文详细解释了JSON（JavaScript Object Notation）的概念，包括其易读易写、便于解析生成的特点，以及基于JavaScript子集构建的特性。JSON通过使用键值对和有序值列表的两种基本结构实现数据的交换。

虽然json已成为一个大家熟知的词，但是可能很多人仍不清楚其真正的概念。

So，what's json?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

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.

These are universal data structures. Virtually all modern programming languages support them in one form or another. It makes sense that a data format that is interchangeable with programming languages also be based on these structures.

由上文可见，JSON是javascript对象标记法，包括两种形式：键值对形式和数组形式。
