Frequently Asked Questions About JSON Stringify/Unstringify
What is JSON stringify?
JSON.stringify converts a JavaScript object or value to a JSON string. For example, {name: "John"} becomes '{"name":"John"}'. This is useful for storing data or sending it to an API.
What is JSON unstringify (parse)?
JSON.parse converts a JSON string back into a JavaScript object. For example, '{"name":"John"}' becomes {name: "John"}. This is used when receiving data from APIs.
