How to use JSON.stringify() and JSON.parse() in Javascript || How to Convert Value to String in Js

JSON.stringify()
The JSON.stringify() method in JavaScript is used to convert a JavaScript object or value into a JSON string. This is particularly useful when you want to send data from JavaScript to a server, store it in a file, or send it over a network. JSON (JavaScript Object Notation) is a widely used format for data exchange, and JSON.stringify() helps transform JavaScript objects into this format.

Syntax:

JSON.stringify(value, replacer, space);
value: The value to be converted to a JSON string (can be an object, array, etc.).
replacer (optional): A function or an array that can be used to filter or modify the values before they are stringified.
space (optional): A string or number that specifies the indentation for pretty-printing the JSON string (useful for human-readable formatting).
If replacer and space are not provided, JSON.stringify() will just convert the value to a compact JSON string.

Example Usage:
If you have a JavaScript object like { name: "Ajith", age: 25 }, you can convert it into a string representation like {"name":"Ajith","age":25}.

JSON.parse()
On the other hand, JSON.parse() is used to convert a JSON string back into a JavaScript object. This is useful when you receive data as a JSON string (for example, from an API or a file) and need to convert it into an object that can be easily manipulated in JavaScript.

Syntax:

JSON.parse(text, reviver);
text: The JSON string to be parsed into a JavaScript object.
reviver (optional): A function that can be used to transform the parsed result before it is returned (for example, modifying dates or converting values).
Example Usage:
If you have a JSON string like {"name":"Ajith","age":25}, you can convert it back into an object like { name: "Ajith", age: 25 }.

Key Differences Between stringify and parse
JSON.stringify() turns a JavaScript object into a string.
JSON.parse() turns a JSON string back into an object.
When to Use:
Use JSON.stringify() when you need to:
Send data to a server.
Store data in a file or database.
Serialize data for other purposes (e.g., logging).
Use JSON.parse() when you need to:
Convert data received from a server (or elsewhere) back into a usable JavaScript object.
Deserialize stored data back into an object.
