Example 16-1 illustrates this.

Json boolean data type example. Let x false. See also numeric literal grammar. The keys must be strings and should be unique and multiple key and value pairs are separated by a comma.

Apart from XML examples could include CSV and YAML a superset of JSON. An object JSON object an array. Data type with fixed precision and scale.

X y is true because x and y have equal values. GeoJSON is used to represent Geographical data while BSON is used by the popular database service provider MongoDB. In JSON values must be one of the following data types.

Example compound JSON value JSON can represent subvalues of four primitive data types and of two compound data types. Key values are separated by colon symbol. Example 16-2 illustrates this the query returns the string true.
