Вивчайте Challenge: Efficient Array Iteration with for...of

Task

You are given an array of objects. Each object represents a friend's information. The task is to create a for...of loop to iterate through the array and add one more property to each object that should be: online: false.

Use a for...of loop to iterate through the friends array.
Inside the for...of loop, use the dot notation to add the property.


              123456789101112131415161718192021222324
            
const friends = [
  {
    name: "Gail Russel",
    address: "803 Kozey Rapid",
    phone: "(317) 833-9935 41777",
  },
  {
    name: "Mrs. Laurie Wunsch",
    address: "7361 Austin Road",
    phone: "(728) 884-9049 4760",
  },
];

// Use a `for...of` loop
for (const friend of ___) {
  friend.___ = ___;
}

// Logging specific properties after modifications
for (const friend of friends) {
  console.log(
    `Friend name is ${friend.name}, ${friend.online ? "online" : "offline"}`
  );
}

Expected Output:

Friend name is Gail Russel, offline
Friend name is Mrs. Laurie Wunsch, offline

To create a for...of loop, use the following syntax: for (const element of array) { ... }.
Use the dot notation (.) to add a property (online) and assign it the value false.


              123456789101112131415161718192021222324
            
const friends = [
  {
    name: "Gail Russel",
    address: "803 Kozey Rapid",
    phone: "(317) 833-9935 41777",
  },
  {
    name: "Mrs. Laurie Wunsch",
    address: "7361 Austin Road",
    phone: "(728) 884-9049 4760",
  },
];

// Use a `for...of` loop
for (const friend of friends) {
  friend.online = false;
}

// Logging specific properties after modifications
for (const friend of friends) {
  console.log(
    `Friend name is ${friend.name}, ${friend.online ? "online" : "offline"}`
  );
}
