2,424 PointsSeem to be missing something..
hobbies = customers .map(customer => customer.personal .map(hobbie => hobbie.hobbies)) .reduce((arr,hobbies) => [...arr,...hobbies],[]);
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(customer => customer.personal
.map(hobbie => hobbie.hobbies))
.reduce((arr,hobbies) => [...arr,...hobbies],[]);

10,636 PointsYou cant map the personal object, because map only works on arrays, nor do you need too. You can reach the hobbies array directly from the personal object with a dot. That'll return each hobbies array so you can use reduce on them and accumulate them. This is what i wrote for it to work
hobbies = customers.map(customer => customer.personal.hobbies)
.reduce((arr,hobbies) => [...arr,...hobbies],[]);
