JSON Tutorial
JSON
JSON: JavaScript Object Notation.
JSON is a syntax for storing and exchanging data.
JSON is an easier-to-use alternative to XML.
The following JSON example defines an employees object, with an array of 3 employee records:
JSON Example
{"employees":[
{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName":"Jones"}
]}
The following XML example also defines an employees object with 3 employee records:
XML Example
<employees>
<employee>
<firstName>John</firstName> <lastName>Doe</lastName>
</employee>
<employee>
<firstName>Anna</firstName> <lastName>Smith</lastName>
</employee>
<employee>
<firstName>Peter</firstName> <lastName>Jones</lastName>
</employee>
</employees>
What is JSON?

like XML. Text can be read and used as a data format by any programming language. |
