Challenge: Create and Structure an Object

Task

Create a JavaScript object called informationCard representing basic personal information. Inside this object, include a nested object with contact details, such as a home address and phone number. The object should have the following structure:

Information card (outer object):

First Name (e.g., "Alice");
Last Name (e.g., "Smith");
Age (e.g., 25);
Contact Details (nested object).

Contact Details (nested object):

Home Address (e.g., "123 Main St, Apt 4B");
Phone Number (e.g., "555-123-4567").

Note

In this challenge, nothing will be output in the console after clicking 'Run Code' as we don't console.log() anything.


              123456789
            
const informationCard = {
  firstName: ___,
  lastName: ___,
  ___: ___,
  contactDetails: {
    homeAddress: ___,
    ___: ___,
  },
};

Use an object literal to define the outer object.
Inside the outer object, create a property called contactDetails and assign it a nested object.
Inside the nested object, add the necessary properties.
You can fill in any data.


              123456789
            
const informationCard = {
  firstName: "Alice",
  lastName: "Smith",
  age: 25,
  contactDetails: {
    homeAddress: "123 Main St, Apt 4B",
    phoneNumber: "555-123-4567",
  },
};
