Here's a possible solution for this exercise:
// find and findIndex
const dogs = [
{ name: 'Duke', breed: 'Labradoodle' },
{ name: 'Max', breed: 'Goldendoodle' },
{ name: 'Cincy', breed: 'Border Collie' },
{ name: 'Apollo', breed: 'Idaho Shag' }
]
// 1. Find the first dog that has a "C" in its breed
// HINT: use the string.includes method
const c = dogs.find(dog => dog.breed.includes('c') || dog.breed.includes('C'));
console.log(c);
// 2. Find the index of the first dog with an "A" in its name
const a = dogs.findIndex(dog => dog.name.includes('a') || dog.name.includes('A'));
console.log(a);
// 3. Find the dog whose breed is Husky
const husky = dogs.find(dog => dog.breed === 'Husky');
console.log(husky);
const huskyIndex = dogs.findIndex(dog => dog.breed === 'Husky');
console.log(huskyIndex);
