Front End Web Development Techdegree Graduate 17,805 PointsHow do I create an array of hobbies?
What am I missing in my code for it to iterate over all the object literals in the customers array and return the hobbies in their own array? As of now it's just returning the last object literal's hobbies in a new array.
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.reduce((hobbyArr, user) => {
hobbyArr = user.personal.hobbies;
return hobbyArr;
}, []);

hobbyArr = user.personal.hobbies;
So the final result is an array with just the hobbies of the last customer.
Modify the function to make it accumulate the hobbies into a larger list instead.
Hint: spread syntax might be useful here!
