What did I do wrong? Thanks!
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;
// hobbies should be: ["Bicycling", "Camping", "Guitar", "Reading", "Gardening", "Comics", "Chess", "Legos"]
// Write your code below
hobbies = customers
.map(user => user.hobbies)
.reduce((arr, favoriteHobbies) => [...arr, ...favoriteHobbies], [])

231,272 PointsThe map method is not creating what you probably intended it for. That's because the customers objects do not have a hobbies property. They have a personal sub-object which has the hobbies.
Fixing that will pass the challenge. But for "extra credit" … you can also solve this using only reduce (with no map).
