For this task you have to return an array of hobbies using the reduce method, it can be done like this
const customers = [
{
name: "Tyrone",
personal: {
age: 33,
hobbies: ["Bicycling", "Camping"]
}
},
{
name: "Elizabeth",
personal: {
age: 25,
hobbies: ["Guitar", "Reading", "Gardening"]
}
},
{
name: "Penny",
personal: {
age: 36,
hobbies: ["Comics", "Chess", "Legos"]
}
}
];
let hobbies;
// We use the reduce method in our array of objects
hobbies = customers.reduce((array, customer) => {
// We assign the new array value with customer.personal.hobbies added to it using concat
array = array.concat(customer.personal.hobbies);
return array;
}, []);
