What are the differences between Vue.js Teleport and Portal?

What are the differences between Vue.js Teleport and Portal?

Vue.js Teleport and Portal are both used for rendering content outside of the parent component's DOM hierarchy. However, Teleport is specifically designed for moving elements to a different part of the DOM while maintaining their reactivity, whereas Portal is more general and can be used for rendering components in different locations.

Can you give me an example of when to use Teleport?

Sure! You might use Teleport when you want to render a modal or tooltip that should appear outside of its parent component, like in a fixed position on the screen, while still being reactive to the component's state.

What about using Portal? When is it more appropriate?

Portal is great for cases where you want to render a component in a different part of the DOM but don't need to maintain the reactivity of the parent. For example, you might use it for a dropdown menu that needs to be rendered in a specific location without affecting the layout of the parent.

Are there any performance differences between the two?

Generally, both Teleport and Portal are efficient, but Teleport may have a slight edge in performance when it comes to reactivity since it maintains the context of the parent component. However, the difference is usually negligible in most applications.
