JSON doubt

Question

Hi everyone ,I want to know if someone can help me clearing this doubt , one of my professor's told me that I can write the syntax for Json like this:

Data='[{"Name":"Jerry","Age":"21"}]';

Is this correct ? Cause I'm trying to make a Json archive on NetBeans and it keeps showing me that there is an error.

Answer 1

This is a json string, not json object
Data='[{"Name":"Jerry","Age":"21"}]';

The correct json object assignment is
var Data= [{Name:"Jerry", Age:21}];

However if you read json from a file, it's in string format
You need to convert it to json object, using JSON.parse method.

var json = '{"result":true, "count":42}'; //json string
obj = JSON.parse(json); // json object

Answer 2

For javascript implement, you need to use json object, not json string.

Answer 3

json object:
var data={"data one":"data cell","data two":"cell two"};
json string:
var data="{"data one":"data cell","data two":"cell two"};"
conversion to json object:
JSON.parse(data);
conversion to json string:
JSON.stringify(data);

Answer 4

Actually json need a proper syntax In which data can be parse.
Correct syntax is:-

var arg= {name: "java", age: 77, city: "Mumbai "};

Answer 5

Okay but this needs to be on the JavaScript or in the Json file ?
