Function volatileProp

volatileProp<TTarget extends object, TValue>(
defaultValueGen: () => TValue,
): VolatileProp<TTarget, TValue>
Creates a volatile property accessor on a target object. The property is considered "volatile" because it does not persist on the object itself and is not part of its persisted data. Note: Volatile props for unique nodes (nodes with a same type and key) will be shared, since they are actually always the same instance.
Type Parameters
- TTarget extends object
  The type of the target object.
- TValue
  The type of the volatile property's value.
Parameters
- defaultValueGen: () => TValue
  A function that returns the default value for the property.
Returns VolatileProp<TTarget, TValue>
A tuple where the first element is the getter function, the second is the setter function and the third is the reset function to set a default value again.
Example
```
const [getVolatile, setVolatile, resetVolatile] = volatileProp(() => 0);

const obj = node({});

// Initially, the volatile property is 0.
console.log(getVolatile(obj)); // outputs 0

// Update the volatile property:
setVolatile(obj, 42);
console.log(getVolatile(obj)); // outputs 42

// Reset the volatile property:
resetVolatile(obj);
console.log(getVolatile(obj)); // outputs 0
```
