How can i parse a json string in javascript?

You can use the `JSON.parse()` method to convert a JSON string into a JavaScript object. Example:

let jsonString = '{"name": "John", "age": 25}';
let obj = JSON.parse(jsonString);
console.log(obj.name);  // John

The above code converts a JSON string into a JavaScript object, which can then be accessed like any other object.
