JSON 관련 함수

JSON.parse() <->JSON.stringfy()와 서로 반대개념

A common use of JSON is to exchange data to/from a web server.

When receiving data from a web server, the data is always a string.

Parse the data with JSON.parse(), and the data becomes a JavaScript object.

Example - Parsing JSON

Imagine we received this text from a web server:

'{ "name":"John", "age":30, "city":"New York"}'

Use the JavaScript function JSON.parse() to convert text into a JavaScript object:

var obj = JSON.parse('{ "name":"John", "age":30, "city":"New York"}');
