JavaScript (JSON.stringify)

`JSON.stringify` is a function in JavaScript that converts a JavaScript object or value into a JSON (JavaScript Object Notation) string. JSON is a lightweight format used for storing and exchanging data. When you use `JSON.stringify`, the complex data structures, such as arrays or objects, are transformed into a text format that can easily be transmitted over the web or saved in files. This process is essential for APIs and web applications, allowing different systems to communicate effectively by using a standard data format.
