All of these are either already stored as raw numbers or can be converted into numbers. Once we do that, we can animate these state changes using 3rd-party libraries to tween state, in combination with Vue's reactivity and component systems.
Watchers allow us to animate changes of any numerical property into another property. That may sound complicated in the abstract, so let's dive into an example using Tween.js:
When you update the number, the change is animated below the input. This makes for a nice demo, but what about something that isn't directly stored as a number, like any valid CSS color for example? Here's how we could accomplish this with the addition of Color.js:
Just as with Vue's transition components, the data backing state transitions can be updated in real time, which is especially useful for prototyping! Even using a simple SVG polygon, you can achieve many effects that would be difficult to conceive of until you've played with the variables a little.
Managing many state transitions can quickly increase the complexity of a Vue instance or component. Fortunately, many animations can be extracted out into dedicated child components. Let's do this with the animated integer from our earlier example:
//All complexity has now been removed from the main Vue instance!

//すべての複雑さがメインの Vue インスタンスから取り除かれました!

Within child components, we can use any combination of transition strategies that have been covered on this page, along with those offered by Vue's [built-in transition system](transitions.html). Together, there are very few limits to what can be accomplished.
