 *
 * Use a series of ternary operator to set the category to one of the following:
 *   - "herbivore" if an animal eats plants
 *   - "carnivore" if an animal eats animals
 *   - "omnivore" if an animal eats plants and animals
 *   - undefined if an animal doesn't eat plants or animals
 *
 * Notes
 *   - use the variables `eatsPlants` and `eatsAnimals` in your ternary expressions
 *   - `if` statements aren't allowed ;-)
 */

// change the values of `eatsPlants` and `eatsAnimals` to test your code
var eatsPlants = false;
var eatsAnimals = true;

var category = eatsPlants && eatsAnimals ? "omnivore" : ( eatsAnimals ? "carnivore" : ( eatsPlants ? "herbivore" : undefined ) );

console.log(category));

What Went Well

• Your code should have a variable eatsPlants
• Your code should have a variable eatsAnimals
• Your code should include ternary statements
• Your code should produce the expected output

Feedback: Your answer passed all our tests! Awesome job!

The format of the conditionals I suggest is this:
var category = 🌿&🐮 ? "omnivore" : (🐮? "carnivore" : (🌿 ? "herbivore" : undefined ) );

So that, to check for the category in all options.
