  1. Use dot notation to access properties within an object.
  2. To access properties within nested objects and arrays, chain the dot notation and square brackets (if needed).
  3. Use assignment with dot notation to store property values in variables.
const user = {
name: "Sarah",
age: 32,
hobbies: {
outdoor: "hiking",
indoor: "painting",
},
preferences: {
music: "jazz",
movieGenre: "sci-fi",
},
};
// Task 1
console.log(user.name); // person's name

// Task 2
console.log(user.hobbies.indoor); // indoor hobby

// Task 3
const userAge = user.age;
console.log(userAge); // person's age

// Task 4
console.log(user.preferences.music); // music genre
