JSON Overview

What is JSON?

JSON stands for JavaScript Object Notation. It is a lightweight text-based data-interchange format. It is language and platform independent. JSON is a lightweight alternative to XML. JSON was invented by Douglas Crockford.
Note: JSON is mainly used for storing and exchanging data. The file extension for JSON is .json and Internet Media type is application/json.

JSON example:

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

XML example:

< students>
< student>
<firstName>Sandy</firstName>
<lastName>Sethi</lastName>
</ student>
< student>
<firstName>Roxy</firstName>
<lastName>Malik</lastName>
</ student>
< student>
<firstName>Sunil</firstName>
<lastName>Antil</lastName>
</ student>
</ students>

Difference between JSON and XML:

1. JSON doesn’t use end tag. XML uses end tag.
2. JSON can use arrays. XML can’t use arrays.
3. JSON need only a standard JavaScript function to parse. XML needs XML parser to parse.
