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"
}]
}}

json can be used as an alternative to xml. Commonly it is used in web services where data is exchanged between a service and it’s clients via xml or json
This is most useful as an API. Best used to provide API access.
