Well I am following the previous examples but still cant solve the problem. I first use map method to get the hobbies arrays and then use reduce method to flatten arrays into one big array as we saw in the previous examples but I get an error of innerhobbie is not iterable. I believe that after the map method I get an array of arrays and then use reduce on that array of arrays.
Please help
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.hobbies).reduce((arr, innerhobbie) => [...arr, ...innerhobbie], []);

refactor to customer => customer.personal.hobbies
-- forgot to add .personal
before .hobbies
