How does Vue 3's provide/inject work with reactivity?

Can you explain how the provide/inject feature works in Vue 3?

Sure! In Vue 3, provide/inject is a way to pass data from a parent component to a deeply nested child component without having to pass props through every level.

How does reactivity work with provide/inject?

Reactivity in provide/inject works seamlessly. When you provide a reactive object, any changes to that object will automatically reflect in the injected components.

Can you give me an example of using provide/inject with a reactive object?

Absolutely! You can use the reactive function to create a reactive object and then provide it like this: provide('myData', reactive({ count: 0 })). In the child, you can inject it using const myData = inject('myData');.

What are some common use cases for provide/inject?

Common use cases include managing global state, sharing configuration settings, or passing down functions to deeply nested components.
