Prop being mutated: "formatter"

[tradingstratagem]

Hi,

when I run unit test in a component using this library I have the following warning:

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "formatter"

Here the code:

Looks like your code got stripped...

<tween-num :value="balance" :formatter="value => formatCurrency(value)"></tween-num>
