What is Vue Transition Group and how do I use it?

Vue Transition Group is a component that allows you to apply transition effects when items are added or removed from a list. You can use it to create smooth animations for dynamic lists.

Can you show me a simple example of how to implement it?

Sure! Here's a basic example:

<transition-group name="fade" tag="div">
  <div v-for="item in items" :key="item.id">{{ item.text }}</div>
</transition-group>

In your CSS, you can define the fade effect like this:

.fade-enter-active, .fade-leave-active {
  transition: opacity 0.5s;
}
.fade-enter, .fade-leave-to {
  opacity: 0;
}

What kind of animations can I create with it?

You can create various animations like fades, slides, flips, and more by customizing the CSS transitions. The possibilities are quite extensive!

Are there any performance considerations I should be aware of?

Yes, when using transition groups, be mindful of the number of elements being animated at once, as too many can lead to performance issues. It's best to limit the number of simultaneous transitions.
