good luck, INDIA IS RISING. DO GOOD TO THE WORLD...

Using reducer we are directly changing the initial state value without using setState method which is contradicting to what you said in the previous react videos.

Why do we need the cakeActions.js file you didnt use it

karamsahoo

Maybe it would have been a good idea this reducer to contain a payload with the number of bought cakes.

How can i set initial state from child component please help....

mridulhoneysharma

why its took so complex steps to do simple task

aravindatr

It works on decrement(when buying cake the number of cake decrease) but when trying to increment it malfunctions. Suppose numOfCakes-10 and when we buy it gives us 9 but when incrementing the number instead of giving 11 it gives us 101, 1011, 10111, 101111... Why? is it an intention bug?

First of all thank you for making such amazing video in a structured manner.

So i have one doubt is it necessary to pass the state parameter to the reducer function and what will happen if we don't pass the state parameter.
