DRY exercise

example1

const pets = ['Cat', 'Dog', 'Bird', 'Fish', 'Frog', 'Hamster', 'Pig', 'Horse', 'Lion', 'Dragon'];
// Print all pets
console.log(pets[0]);
console.log(pets[1]);
console.log(pets[2]);
console.log(pets[3]);
...

//css

.cat {
  font-family: "Times New Roman", Times, serif;
  font-size: 1rem;
  color: #FFF;

}
.dog {
  font-family: "Times New Roman", Times, serif;
  font-size: 1rem;
  color: #000;
}
.dragon {
  font-family: "Times New Roman", Times, serif;
  font-size: 1rem;
  color: #009933;
}

It is not dry in that lines of code have been repeated

const pets = ['Cat', 'Dog', 'Bird', 'Fish', 'Frog', 'Hamster', 'Pig', 'Horse', 'Lion', 'Dragon'];
// Print all pets
pets.forEach(pet => console.log(pet());

//css
pets {
  font-family: "Times New Roman", Times, serif;
  font-size: 1rem;
}

cat{
color: #FFF;
}

dog{
 color: #000;
}

dragon{
color: #009933;
}

example2

const greet = (message, name) => {
  console.log(`${message}, ${name}!`)
}

greet('Hello', 'John');
greet('Hola', 'Antonio');
greet('Ciao', 'Luigi')

//css

.greetings {
  font-family: Arial, sans-serif;
  font-size: 1.5rem;
}

.greetings.english {
  background-color: #000;
  color: #FFF;
}
.greetings.spanish {
  background-color: #FFF;
  color: #000;
}

It is DRY, no code has been repeated.
