I see that you did all your homework in one file, but the assignment was to make one file for each part of the homework:

For all the following exercises create a new .js file. Try to find a proper name for each file or make a small comment about what it does inside for future reference.

You should not use capital letters for the variable names.

So FavoriteAnimals should be favoriteAnimals.

Tip: The code is easier to read if you add more spaces in between the if statement, like this:

if (typeof(type1)===typeof(type3)) {
  console.log('type1 and type3 are SameType');

  console.log('type1 and type3 are NOT SameType');
}
