Reactive rule
Any validation resolver may become reactive. This means that it is being re-evaluated anytime the field prop references established in its declaration change.
Definition
Declaration
Use get
function from the resolver parameters to reference other fields' props.
The resolver above marks confirmPassword
field as valid whenever its value
equals to the value of the password
field. This rule is automatically re-evaluated in real time whenever the values of either fields update.
Use reactive rules when the validity of a field depends on some props of another field(s).
