Use dot notation to access properties within an object.
To access properties within nested objects and arrays, chain the dot notation and square brackets (if needed).
Use assignment with dot notation to store property values in variables.


              123456789101112131415161718192021222324
            
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

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