Can someone help me with this one please?

Making the Guest List

We need to keep track of the party guests, but the data we currently have combines the guests first and last names into a single name. You have been asked to separate the names to make the data easier to work with.

The makeGuestList function takes an object with a name property whose value will be a string consisting of a first name and a last name, separated by a space. The function should return an object.

The function should remove the name property, replace it with firstName and lastName properties, as shown in the examples below.


makeGuestList({ name: "Hannah Fry", age: 46 })
// should return { firstName: "Hannah", lastName: "Fry", age: 46 }

makeGuestList({ name: "Paul Erdős", age: 46 })
// should return { firstName: "Paul", lastName: "Erdős", age: 46 }

Note: all other properties should remain unchanged

function makeGuestList(person) {

// Your code goes here…


Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:
