How to use the reduce method on arrays within a property of an object?

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

// map over each nested object, then forEach over each hobbies array customers.map((nestedObject)=>{nestedObject.personal.hobbies.forEach( hobby => hobbies.push(hobby)) });
