# JSON format and data types

## JSON Syntax:

JSON syntax is a subset of the JavaScript object notation syntax. JSON syntax has following rules:
1. Data is represented in name/value pairs.
2. Data is separated by commas.
3. Curly braces hold objects and each object name is followed by colon.
4. Square brackets hold arrays.

## JSON example:

{"students":[ {"firstName":"Sandy", "lastName":"Sethi"}, {"firstName":"Roxy", "lastName":"Malik"}, {"firstName":"Sunil", "lastName":"Antil"} ]}
