[Official materials] Introduction to JSON

JSON(JavaScript Object Notation) is a lightweight data exchange format. Easy to read and write. It is also easy to parse and generate machines. It is based on a subset of JavaScript programming language, standard ECMA-262 3rd edition-December 1999. JSON uses a completely language-independent text format, but it also uses a habit similar to the C language family (including C, C ++, C #, Java, JavaScript, Perl, Python, and so on ). These features make JSON an ideal data exchange language.

JSON is constructed in two structures:

• A collection of name/value pairs ). In different languages, it is understoodObject), Record, structure (struct), Dictionary, hash table, keyed list, or associative array ).
• An ordered list of values ). In most languages, it is understood as an array ).

These are common data structures. In fact, most modern computer languages support them in some form. This makes a data format based on these structuresProgramming LanguageExchange between them becomes possible.

JSON has the following forms:

An object is an unordered set of 'name/value' pairs. An object starts with "{" (left parenthesis) and ends with "}" (right Parenthesis. Each "name" is followed by a ":" (colon); "," (comma) is used to separate the "name/value" pairs.

An array is an ordered set of values. An array starts with "[" (left square brackets) and ends with "]" (right square brackets. Values are separated by commas.

Value (Value) Can be a string enclosed by double quotation marks (String), Value (number ),True,False,NullObject or array ). These structures can be nested.

String (StringIs a set of any number of Unicode characters enclosed by double quotation marks, which are escaped using a backslash. A character (character) is a separate string (character string ).

String (String) Is very similar to a C or Java string.

Value (Number) Is also very similar to the values in C or Java. Remove unused octal and hexadecimal formats. Except for some encoding details.

Spaces can be added to any symbol. The complete language is described below.
