When would you use `JSON.stringify()` in your JavaScript code?

Using JSON.stringify() in your JavaScript code is particularly useful when you want to convert a JavaScript object into a string format. This is important for two main reasons: storage and transmission.

When storing data, particularly in web applications, it's common to use local storage, session storage, or cookies, all of which can only handle string data. JSON.stringify() allows you to transform objects, arrays, or even complex data structures into a string representation that can be stored and later retrieved.

Additionally, when transmitting data over the network, such as when sending data to a server through an API call, it's essential to use a format that can be easily understood on both the client and server sides. JSON (JavaScript Object Notation) is a commonly used format for this purpose. By converting your JavaScript objects into a JSON string with JSON.stringify(), you ensure the data is in a format that can be parsed and utilized effectively by different systems.

This makes the choice of using JSON.stringify() specifically aligned with the need to convert objects into a string for purposes of storage or transmission, confirming that the provided answer is indeed accurate.
