Van still provides the tools to limit the update rate.
```JS
let {updateRate} = van
updateRate(100)
```
This set´s the update rate to 100ms. state changes are delayed by up to 100 ms, before they are propagated to the DOM. If multiple changes are applied withi this time, only the last is updating the DOM.

Van propagates every state change immediately to the bound DOM elements. This may result in a bad user experience, if too many changes are applied at a high frequency.
VanJs contains everything to limit the state change rate. It just requires to set one variable to use it. I provided this variable and a setter to change it. I provided a possible implementation, if there are other ways this would be ok.
