JSON

JavaScript Object Notation (JSON) is an open-standard file format that uses human-readable text to transmit data objects consisting of attribute–value pairs and array data types.

JSON’s basic data types are:

• Number: a signed decimal number that may contain a fractional part and may use * exponential E notation.
• String: a sequence of zero or more Unicode characters.
• Boolean: either of the values true or false.
• Array: an ordered list of zero or more values, each of which may be of any type.
• Object: an unordered collection of name–value pairs where the names are strings.
• null: An empty value, using the word null
