Thanks for the tutorial, Marina. Here's my solution:

HTML:

<span v-for="star in game.rating" @click="increaseRating(game)">⭐</span>

JS bit:

It works, but it's a little overkill :) You can pass the whole 'game' object to the function, that way you don't have to .find on the array. Also, be careful with ==, as a best practice try to use === that way you won't run into very hard to understand bugs with types! :D
