// EXAMPLE TEST CASES //
////////////////////////

// #1 - Pokemon is defined
console.assert(Pokemon);

// #2 - `Pokemon` object initialized with `.name`, `.attack`, `.defense`, `.health`, and `.type`
const charmander = new Pokemon("charmander", 12, 8, 30, "fire");
console.assert(charmander.name === "charmander", ".name property not correctly defined");

// #4 `attackOpponent()` method, which takes a `Pokemon` object as an argument (the opponent being attacked). This method should call the `takeDamage()` method on the opponent `Pokemon`.
const bulbasaur = new Pokemon("bulbasaur", 7, 9, 35, "grass/poison");

// #5 `display()` method, which takes no arguments and returns a string in the format "POKEMON_NAME (POKEMON_TYPE) CURRENT_POKEMON_HEALTH/ORIGINAL_POKEMON_HEALTH"
