How to setup Ember like computed properties in Immutablejs and Redux and Flux and React

I am used to computed properties in Ember Object Model. It's a convenient way to specify computed properties that depend on other properties.

Say fullName depends on firstName and lastName, I can setup computed properties as a function computeProperties and call computeProperties each time I make a change.

Example:

function computeFullName(state) {
  const fullName = state.get('firstName') + state.get('lastName');
  const nextState = state.set('fullName', fullName);
  return nextState;
}

function computeProperties(state) {
  const nextState = computeFullName(state);
  return nextState;
}

// store action handler
[handleActionX](state) {

  let nextState = state.set('firstName', 'John');
  nextState = state.set('lastName', 'Doe');

  nextState = computeProperties(nextState);

  return nextState;
}

Is there a way to automatically setup computed properties so that I don't have to call extra functions each time. In Redux or in ImmutableJS.
