How to create a field in state named action?

Question

JavaScript

Good afternoon.
I'm new, I'm asking for help.
An action comes into my reducer with two values: action.name and action.payload.
I need to add a property to the state with the name action.name and the value action.payload

export const BuyReducer = (state = defaultState, action) => {
                return{...state,
                           state[action.name]: action:payload //неверно
                          }

}

For example action.name = "Dima", action.payload = 30, then state will be equal to

const defaultState = {
Dima: 30
}

How to do it?

Answer 1

const action = {name: 'Dima', payload: 30};
const state = {
    ...state,
    [action.name]: action.payload
};

Ps I would advise you to learn "vanilla" javascript before react / redux
