I have a structure(nested object) that exists in the attached image and if I want to change the value of info[1] and assign it to info state into the related reducer, but it doesn't update immediately and I think a deep comparison between the previous state and current value didn't occur.
Someone suggested the immutable js but I don't how to use it. honestly, I've converted assigning a value(the assigned value to info state after triggering action) to List imported from immutable js because of changing the reference address of the prev state and new value but I didn't get the result.
I prepared a sandbox for it: enter link description here
I expect when I select the cells then push the increase button, selected cells increase one unit increase immediately but it doesn't happen and you must refresh the window to see the changes.
