Hey Azzie Fuzzie you'll need to use the JSON.parse() method to parse your son string instead of using .json()

Hi Azzie!

You need to pass jsonString to JSON.parse() and assign it to a variable you declare as jsonObject.

Like this:

const jsonString = '{"name": "Andrew", "languages": ["javascript", "swift", "java", "ruby", "html", "css", "qbasic"]}';

const jsonObject = JSON.parse(jsonString); // Converts the JSON string to a JSON object

I hope that helps.

Stay safe and happy coding!
