JSON اسئلة واجوبة المقابلات

Question: Why use JSON over XML?

Answer: � Lighter and faster than XML as on-the-wire data format
� JSON objects are typed while XML data is typeless
> JSON types: string, number, array, boolean,
> XML data are all string
� Native data form for JavaScript code
> Data is readily accessible as JSON objects in your JavaScript
code vs. XML data needed to be parsed and assigned to variables through tedious DOM APIs
> Retrieving values is as easy as reading from an object property in your JavaScript code
