Answer
JSON is a lightweight data format used for configuration, APIs, and storing structured data.
Quick Answer
JSON (JavaScript Object Notation) is the standard data format for APIs. Node.js has JSON.parse() to convert a JSON string to a JavaScript object, and JSON.stringify() to convert an object to a JSON string. Express's res.json() automatically serializes your response object and sets the Content-Type header to application/json.
