What is JSON – JSON Complete Tutorial

JSON: Java Script Object b Object (JavaScript Object Notation)
JSON is the syntax for storing and exchanging textual information. Similar to XML.
JSON is smaller, faster, and easier to parse than XML.
What is JSON?
·         JSON refers to the JavaScript Object Notation
·         JSON is a lightweight text data exchange format
·         JSON is language independent: JSON uses JavaScript syntax to describe data objects, but JSON is still language and platform independent. The JSON parser and JSON library support many different programming languages. Currently, a very large number of dynamic (PHP, JSP, .NET) programming languages ​​support JSON.
·         JSON is self-explanatory and easier to understand


JSON – Convert to JavaScript object
The JSON text format is syntactically the same as the code that creates a JavaScript object.
Because of this similarity, without a parser, JavaScript programs can generate native JavaScript objects using JSON data using the built-in eval () function.

Same as XML

·         JSON is plain text
·         JSON has a “self-descriptive” (human-readable)
·         JSON has a hierarchy (values ​​have values)
·         JSON parses through JavaScript
·         JSON data can be transmitted using AJAX

Difference with XML

·         There is no end tag
·         Shorter
·         Read and write faster
·         Ability to use the built-in JavaScript eval () method for parsing
·         Use an array
·         Do not use reserved words

Why use JSON?

JSON is faster and easier to use than XML for AJAX applications:

Use XML

·         Read the XML document
·         Use the XML DOM to loop through the document
·         Read the value and store it in a variable

Use JSON

·         Read JSON string
·         Use eval () to handle JSON strings
