What is JSON?
JSON (JavaScript Object Notation) is an open and lightweight format that uses human-readable text to structure, store, and transmit data over a network. The MIME type for JSON is application/json. JSON files use the .json filename extension.
Why JSON?
There are several reasons why you should consider using JSON, the key reason being that JSON is independent of your system's programming language, despite being derived from JavaScript.
Other reasons include:
-
Readability – JSON is human-readable, given proper formatting.
-
It's easy to analyze into logical syntactic components, especially in JavaScript.
-
Countless JSON libraries are available for most programming languages.

-
Dates and similar object types are not supported properly and must be converted to strings.
-
Numeric values are in double precision floating point format and must not have leading zeros.
-
Null values are represented by a lowercase null literal.
-
The standard extension for a JSON file is ".json".
-
The MIME type for JSON files is application/json
