var favoriteAnimal = 'dog';
console.log('My favorite Animal: ' + dog);
I have redone this several times. I'm sure the solution is obvious. This is the wording of the problem:
Create a variable named favoriteAnimal and set it equal to your favorite animal.
Then, use console.log to print: 'My favorite animal: Koala', but replace 'Koala' with your favoriteAnimal variable.
Use the + operator to interpolate the favoriteAnimal variable.
