"id": 1,
"name": "Code Architects",

}JSON Stringify
A JSON object can be converted to JSON by using JSON.stringify() which is sent to browser from a Web Server. Taking JavaScript object and transforming to JSON String.
let obj = {
firstName: "John",
lastName: "Doe"
};
let jsonExample = JSON.stringify(obj);
console.log(jsonExample);
// {"firstName":"John","lastName":"Doe"}JSON Parse
JSON.parse() takes the JSON string as an input and transforms it into JavaScript Object.
let str = '{"firstName":"John","lastName":"Doe"}';
let obj = JSON.parse(str);
console.log(obj);
/* {
firstName: "John",
lastName: "Doe"
} */You also can modify or delete the values in these objects using both dot and bracket notation. In order to delete a property, use the delete keyword.
