Advanced Redux : What's the problem Immer solved?

Mutating internal data is something that led to problems in your app, especially when you don't have the ability to know what's going on and you need to do that on foot.

So Immer :
- Create an immutable data structure
- Detect accidental mutations and throws errors
- Reduce boilerplate for deep immutables updates
- No need to learn a new API

But... what's Immutable data structure?, what is Immutability?
