bookChallenge: Creating 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.

const informationCard = { firstName: ___, lastName: ___, ___: ___, contactDetails: { homeAddress: ___, ___: ___, }, };
copy
  1. Use an object literal to define the outer object.
  2. Inside the outer object, create a property called contactDetails and assign it a nested object.
  3. Inside the nested object, add the necessary properties.
  4. You can fill in any data.

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

Everything was clear?

How can we improve it?
