// sync rule
Modeller.register('myRule', (valueReceived, valueOfRule) => {
  return (valueReceived <= valueOfRule);
});
 
// async rule
Modeller.register('myRuleAsync', valueReceived => new Promise((resolve, reject) => {
  setTimeout(() => {
    if (valueReceived >= 18) {
      resolve();
    } else {
      reject();
    }
  }, 150);

userMold.test({

userMold.test({
