What are the possible ways to provide transitions?

There are many ways Vue provides transition effects when items are inserted, updated, or removed from the DOM.

Below are the possible ways,

1. Automatically apply classes for CSS transitions and animations
2. Integrate 3rd-party CSS animation libraries. For example, Animate.css
3. Use JavaScript to directly manipulate the DOM during transition hooks
4. Integrate 3rd-party JavaScript animation libraries. For example, Velocity.js
