#10 - Watchers - Vue 3 (Options API) Tutorial

In this Vue 3 tutorial, we learn how to watch data and computed properties with watchers and execute code in response to any changes. We cover how to watch deep objects and arrays, run watchers on page load and when to use watchers instead of computed properties. We cover the following topics: 1. Watchers 2. Watchers vs. Computed Properties 3. How to run a Watcher on page load 4. How to watch nested objects 5. How to watch arrays _Note that this tutorial is for the Vue 3 Options API (which is similar to Vue 2).
