Introduction to the--json structure of the JSON experience

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It's 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, which is completely language independent but uses conventions that's 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 structures:

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

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

In JSON, they take on these forms:

An object was an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name was followed by : (colon) and the Name/value pairs was separated by, (comma) .

An array was an ordered collection of values. An array of begins with [ (left bracket) and ends with ] (right bracket). Values is separated by, (comma).

A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.

A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a and a single character string. A string is very much like a C or Java string.

A number is very much like a C or Java number, except that the octal and hexadecimal formats was not used.

Whitespace can inserted between any pair of tokens. Excepting a few encoding details, that completely describes the language.

Quoted from http://www.json.org/official website written very well, I this place to reprint, explain the overall structure of JSON, so that the knowledge system more complete.
