JSON JSON(JavaScript Object Notation) is a human-readable data exchange format. 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. JSON's basic data types are: Number : a signed decimal number that may contain a fractional part and may use exponential E notation, but cannot include non-numbers such as NaN. The format makes no distinction between integer and floating-point. JavaScript uses a double-precision floating-point format for all its numeric values, but other languages implementing JSON may encode numbers differently. String : a sequence of zero or more Unicode characters. Strings are delimited with double-quotation marks and support a backslash escaping syntax. Boolean : either of the values true or false Arra
