JSON - Syntax

Let's have a quick look at the basic syntax of JSON. JSON syntax is basically considered as a subset of JavaScript syntax; it includes the following −

• Data is represented in name/value pairs.

• Curly braces hold objects and each name is followed by ':'(colon), the name/value pairs are separated by , (comma).

• Square brackets hold arrays and values are separated by ,(comma).

Below is a simple example −

 { "book": [ { "id": "01", "language": "Java", "edition": "third", "author": "Herbert Schildt" }, { "id": "07", "language": "C++", "edition": "second", "author": "E.Balagurusamy" } ] } 

JSON supports the following two data structures −

• Collection of name/value pairs − This Data Structure is supported by different programming languages.

• Ordered list of values − It includes array, list, vector or sequence etc.
