What are Vue transition hooks and how do I use them?

Vue transition hooks are lifecycle hooks that allow you to control the transition effects when elements enter or leave the DOM. They provide a way to execute code at specific points during the transition process.

Can you give me an example of how to implement a transition hook?

Sure! You can use the before-enter, enter, and leave hooks in your Vue component. For example:

<transition
  @before-enter="beforeEnter"
  @enter="enter"
  @leave="leave"
>
  <div v-if="show">Hello World!</div>
</transition>

In your methods, you can define the animations.

What kind of animations can I create with these hooks?

You can create various animations like fade, slide, or scale effects. By manipulating CSS classes or using JavaScript animations, you can achieve different visual effects.

Are there any performance considerations I should be aware of?

Yes, it's important to keep animations lightweight and avoid heavy computations during transitions to maintain smooth performance. Using CSS transitions is generally more performant than JavaScript.
