I’m trying to increase the count inside the reducer function for an object. Here in the action “addItem”, I’m trying to increase the count if the item added is already present in the store.

import { createSlice, current } from "@reduxjs/toolkit";
import React from "react";

const cartSlice = createSlice({
  name: "cart",
  initialState: {
    items: [],
  },
  reducers: {
    addItem: (state, action) => {
      let a = 0;
      current(state.items).map((item) => {
        console.log(item, "hey there");
        if (item === action.payload) {
          console.log("Matched");
          console.log("Count1 is", ++item.card.info.count);
          item.card.info.count = item.card.info.count + 1;
          console.log("Count2 is", item.card.info.count);
          a = 1;
          return;
        }
      });
      if (a == 0) {
        state.items.push(action.payload);
      }
    },
    removeItem: (state, action) => {
      state.items.pop();
    },
    clearCart: (state, action) => {
      state.items.length = 0;
    },
  },
});

export const { addItem, removeItem, clearCart } = cartSlice.actions;

export default cartSlice.reducer;

I’m attaching the console output below.

{card: {…}} 'hey there'
cartSlice.js:15 Matched
cartSlice.js:16 Count1 is 1
cartSlice.js:18 Count2 is 0
cartSlice.js:13 {card: {…}} 'hey there'
cartSlice.js:15 Matched
cartSlice.js:16 Count1 is 1
cartSlice.js:18 Count2 is 0
cartSlice.js:13 {card: {…}} 'hey there'

cartSlice.js:16 Count1 is 1
cartSlice.js:18 Count2 is 0
cartSlice.js:13 {card: {…}} 'hey there'

cartSlice.js:13 {card: {…}} 'hey there'
cartSlice.js:15 Matched
cartSlice.js:16 Count1 is 1
cartSlice.js:18 Count2 is 0

Provide me some suggestion that what I’m doing wrong here. Thanks in advance.
