The opposite of the JavaScript JSON.stringify() method is JSON.parse(), which parses a JSON string and constructs JavaScript value or object from it. For example:
const obj = { width: 25, height: 25 };
const str = JSON.stringify(obj); // '{"width":25,"height":25}'
console.log(JSON.parse(str)); // {width: 25, height: 25}
Please note that JSON.parse() throws a SyntaxError exception if the provided string is not valid JSON.
