const object1 = {

};

const object2 = {

const mutator = new Mutator();

mutator.addRule({
  field: 'bar',
  value: '2',
  handler: (obj) => {
    obj.foo = 3;
  }
});

mutator.transform(object1); // object1.bar=1, so no transformation takes place
console.log(object1.foo);
// outputs 1

mutator.transform(object2); // object2.bar=2, so the transformation takes place
console.log(object2.foo);
// outputs 3
