User Profile Formatter

Format a nested user object into values that are easier to show in an interface or return from an API. The final summary should collect the smaller pieces.

Write these functions:

• getDisplayName(user) should return the first and last name as one string.

• getLocation(user) should return "City, Country".

• getContactSummary(user) should return an object with email and phone.

• isAccountActive(user) should return true when account.status is "active".

• createProfileSummary(user) should return displayName, location, contact, active, and plan.

Sample checks:

const user = {  id: 42,  firstName: 'Ava',  lastName: 'Stone',  email: 'ava@example.com',  phone: null,  address: {    city: 'London',    country: 'UK',  },  account: {    status: 'active',    plan: 'pro',  },};console.log(createProfileSummary(user));console.log(getDisplayName(user));console.log(isAccountActive(user));console.log(getContactSummary(user));

Expected output:

{ displayName: "Ava Stone", location: "London, UK", contact: { email: "ava@example.com", phone: null }, active: true, plan: "pro" }Ava Stonetrue{ email: "ava@example.com", phone: null }

Keep phone as null when the user has no phone number.
