Subset of the Java Script language
Syntax is same as JavaScript object creation
Example ( from w3shcools.com )
JSON Object Creation in JavaScript
Name:
Age:
Address:
Phone:
Other Notes:
Much Like XML
JSON is plain text
JSON is "self-describing" (human readable)
JSON is hierarchical (values within values)
JSON can be parsed by JavaScript
JSON data can be transported using AJAX
Much Unlike XML
No end tag
Shorter
Quicker to read and write
Can be parsed using built-in JavaScript eval()
Uses arrays
No reserved words
Why JSON?
For AJAX applications, JSON is faster and easier than XML:
Using XML
Fetch an XML document
Use the XML DOM to loop through the document
Extract values and store in variables
Using JSON
Fetch a JSON string
eval() the JSON string
