Why Redux use Immutable Data Structure?

[ap13p]

Why Redux use immutable data structure. I mean, immutable mean creating a new object for an update right? In my case, my reducer state is just a plain array, but the size is already 1000+. And when it come to updating the data, it's a bit slower. Is there any recommendation for this big array data? :)

Normalization maybe

As I get it, immutability is just a handy feature for debugging. You may set up your dev environment with it and suppress it in a production build, as long as you don't need debugging data from real users at runtime.
