Don't forget that elements with the v-for directive require the v-bind:key / :key attribute, otherwise Vue will scream at you(at least if you're using the development version)
Since this series is for beginners, I would include that in the code too.
I thought about that and opted to leave it out since Vue doesn't seem to care when you're pulling the script from CDN. I figured it would be a distraction for the simple case illustrated. I'll definitely put that in when I write about components.

Can you explain a bit more about this?
Maybe Vue suppress warnings in the production mode.
You should definitely include keys in v-for loops.
To give Vue a hint so that it can track each node’s identity, and thus reuse and reorder existing elements, you need to provide a unique key attribute for each item

I went ahead and added the v-bind:key for completeness. Thanks for the suggestions!
