JavaScript Object Notation is the full form of JSON.
The JSON format was initially specified through Douglas Crockford and is defined in RFC 4627. The official Internet media kind for JSON is application/json. The JSON filename extension is .json. This tutorial will help you recognize JSON and its use inside numerous programming languages including PHP, PERL, Python, Ruby, Java, etc.
Note: The JSON syntax is acquired from JavaScript Object Notation, but the JSON format is text-only.
Special Codes for reading and generating JSON available in many programming languages.
The JSON formation is syntactically almost like the code for generating JavaScript objects. Due to this, a JavaScript program can simply transform JSON data into JavaScript objects.
Since the format is text only, JSON data can simply be sent between computers and employed by any programming language.
JavaScript features an inbuilt function for transforming JSON strings into JavaScript objects:
JSON.parse()
JavaScript also has a set up in function for transforming an object into a JSON string:
JSON.stringify()
Storing Data
When storing information, the information must be in a certain format, and irrespective of where you select to keep it, the text is continually one of the legal formats.
JSON makes it possible to keep JavaScript objects as text.
