const pets = [
  { type: 'Dog', name: 'Max'},
  { type: 'Cat', name: 'Karl'},
  { type: 'Dog', name: 'Tommy'},
]

function findDog(name) {
  for(let i = 0; i<pets.length; i++) {

// Shorthand:
const findDog_ = pets.find(pet => pet.type ==='Dog' && pet.name === 'Tommy');
console.log(findDog_); // { type: 'Dog', name: 'Tommy' }
