I wanted to create 'add to cart' functionality using Redux, so I have defined a reducer function which accepts a state and action, where state is provided a default value.

export const defaultValue= {
  products: [
    {
      id: "",
      title: "",
      description: "",
      image: "",
      price: 0,
      amount: 0,
    },
  ]
};

export const manageCart = (
  state = defaultValue,
  action: { type: string; payload: any}
) => {
  switch (action.type) {
    case actionConstants.ADD_TO_CARTS:
      {
       // ADD to card
      }
  break;
    case actionConstants.REMOVE_FROM_CART: {
      // Remove from card     
     }
 default:
      return state;
}
}

So by default I'm seeing this blank product on my cart which is messing up my logic moving further. Since it is mandatory to provide initial value to the state, what should i do differently to get rid of this issue.
