// Objective: Learn to parse JSON strings and stringify JavaScript objects.

// 1. Declare a JSON string representing an object with name and age properties.

let jsonString = '{"name": "Alex", "age": 30}';

// 2. Parse the JSON string into a JavaScript object.

let personObject = JSON.parse(jsonString);

// 3. Print the name and age of the person to the console.

console.log("Name: " + personObject.name + ", Age: " + personObject.age);

// 4. Modify the age property of the person object.

personObject.age = 31;

// 5. Stringify the modified object back into a JSON string.

let modifiedJsonString = JSON.stringify(personObject);

// 6. Print the modified JSON string to the console.

console.log("Modified JSON: " + modifiedJsonString);

// Exercise: Create a more complex JSON string representing an array of objects, parse it, modify one of the objects, and stringify it back into JSON.
