// CODE_RUNNER: JSON Data structures

// 1. Create a JavaScript object named `resume` with the following properties:
const resume = {
    fullName: "Rohan Sharma", // Add your full name

    education: "Grade 9", // Add your grade
    address: {     // Nested object
        city: "San Diego",
        state: "California",
        country: "United States of America"
    },
    skills: ["Managing JSON objects", "Coding in Javascript", "Playing Lacrosse"]     // Array of strings
};
// 2. Access and display properties for full name, email, and city using dot notation. Look at section 1.
console.log(resume.fullName);
console.log(resume.address.city);
// 3. Convert the `resume` JavaScript object into a JSON string and store it in a variable named `jsonString`, then log the JSON string to the console. Look at Section 3.
const jsonString = JSON.stringify(resume);

// 4. Parse the JSON string back into a JavaScript object and store it in a variable named `parsedResume`, then log the object to the console. Look at Section 3.
const parsedResume = JSON.parse(jsonString);
