Another way to turn off reactivity on arrays or objects is to call Object.freeze() on it.

You can also use the v-once directive for a one time binding so that the dom element doesn't track the property for changes.

Good point! That’s indeed correct. Both are mentioned in the documentation and serve different purposes. v-once removes the node from diffing in virtual-DOM, while Object.freeze() effectively prevents from tracking reactivity (akin to what was exemplified in the article).
