How to easily update nested state fields in a react-redux app?

Question

React

I use useReducer and Context from react in a small application.

The state is quite deep and updating it in the usual way is pretty mind-blowing.

An example of my state:

const state= [
    {
        name: '',
        lastName: '',
        nestedObj: [
            {
                field: ''
                anotherField: {
                    a,
                    b, 
                    c,
                    d
                }
            }
        ]
    }
]

What and how should I use to update deeply nested state fields? Now I ask for tools and examples of use with useReducer and context

• concept - concerns not only redax
  
• decision
