Vue watchers allow you to perform actions in response to changes in your component's data. Watchers are particularly useful for cases where you need to perform asynchronous or expensive operations in response to data changes, or when you need more fine-grained control over the reaction to changes than computed properties or methods can offer. I covered four scenarios of using watchers.
Scenario 1: Watch a "ref(primitive value)"
Scenario 2: Watch a property in a "ref(object)"
Scenario 3: Watch a "ref(object)"
Scenario 4: Watch an array of "ref(primitive value)", a property of a "ref(object)", and "ref(object)"
