What is JSON Stringify and JSON parse?
parse() is used for parsing data that was received as JSON; it deserializes a JSON string into a JavaScript object. JSON. stringify() on the other hand is used to create a JSON string out of an object or array; it serializes a JavaScript object into a JSON string.
Do I need to use JSON parse?
parse() is needed when you have a javascript string of json text and you want to turn it into an object.

Why do we use JSON over XML?
JSON scores over XML with its map data structure that matches with the actual data which make the interpretation easy and data arrangement more predictable. JSON data structure helps in building RESTful APIs providing simpler data exchange methods. JSON applies the same data representation method as done in the code.
