JSON OBJECT

JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).

JSON.parse() :-
JavaScript has a built in function for converting JSON strings into JavaScript objects.
let myJSON = '{"name" :"jay","age":30,"email":"jay@gmail.com"}';
let obj = JSON.parse(text)
document.wright(obj.name); // outpot:- jay document.wright(obj); // outpot:- [object Object]

JSON.stringify() :-
JavaScript also has a built in function for converting an object into a JSON string.
let obj = {name: "John", age: 30, city: "New York"};
let myJSON = JSON.stringify(obj);
document.wright(myJSON);
// output :- {name: "John", age: 30, city: "New York"}

JSON OBJECT :- {"fname":"John" , "lname":"John"} // fileName.json

JS OBJECT :- let obj = {fname:"John" ,lname :'Chouhan'}
// call :- obj.name or obj["name"]
