The difference between JSON objects, JSON plain text, and JS objects:

The difference between JSON plain text and JS objects:

JSON object: Var jsonobject= {

"Name": "John Johnson",

"Street": "Oslo West 555",

"Age": 33,

"Phone": "555 1234567"};

typeof (Jsonobject) The result is: "Object"

JSON plain Text: is a string with JSON data format (plain text)

var txt = ' {' Employees ': [' +

' {' firstName ': ' John ', ' lastName ': ' Doe '}, ' +

' {' firstName ': ' Anna ', ' lastName ': ' Smith '}, ' +

' {' firstName ': ' Peter ', ' lastName ': ' Jones '}]} ';

typeof (TXT) Result: "String"

JSON plain text converted to JS object:

Var jsobj = eval ("(" + txt + ")")

The typeof (Jsobj) result is: "Object", you can use the syntax of the JSON object, and JSON plain text is the syntax that cannot use the JSON object
