What is Json ?

JSON stand for  JavaScript Object Notation.
It is a lightweight text-based open standard designed for human-readable data interchange.
It is derived from the JavaScript  programming language for representing simple data structures and associative arrays, called objects.
Despite its relationship to JavaScript, it is language-independent, with parsers available for virtually every programming language. The JSON filename extension is .json.

It is easy for humans to read and write. It is easy for machines to parse and generate.

Exmaple:

{"skillz": {
"web":[
{"name": "html",
"years": "5"
},
{"name": "css",
"years": "3"
}],
"database":[
{"name": "sql",
"years": "7"
}]
}}
