The JSON parse() static method takes a string in JSON format and converts it to an object.

    
    const city = '{"city":"Detroit","state":"Michigan","founded":1701}';

    const cityObj = JSON.parse(city);

    // typeof doesn't work to show type object
    console.log(cityObj);
    {
       city: "Detroit",
       founded: 1701,
       state: "Michigan"
    }

    console.log(cityObj.founded);
    // 1701
