Description

import { ACTIONS, reducer } from 'general-reducer';

const state = {
    a: {
        a1: 1,
        a2: 2
    },
    b: {
        b1: 3,
        b2: 4
    }
};

const updated = reducer(state, ACTIONS.set('b.b1', 5));

// or

const updated = reducer(state, ACTIONS.set([ 'b', 'b1' ], 5));

As a result we will receive new object with structure below:

{
    a: {
        a1: 1,
        a2: 2
    },
    b: {
        b1: 3,
        b2: 5
    }
}
