JavaScript JSON Methods

JSON.stringify()

Convert object to JSON string:

const user = { name: 'John', age: 25 };
const json = JSON.stringify(user);
// '{"name":"John","age":25}'

JSON.parse()

Convert JSON string to object:

const json = '{"name":"John","age":25}';
const user = JSON.parse(json);
// { name: 'John', age: 25 }

Key Takeaway

stringify() converts to JSON. parse() converts from JSON. Essential for API communication.
