What does the term 'immutable state' mean in the context of React and Redux?
- State that can only be changed by Redux actions
- State that cannot be changed after it's created

- State that is stored in a global context
In the context of React and Redux, 'immutable state' refers to state that cannot be changed after it's created. In Redux, state immutability is a core principle. Instead of modifying the existing state, a new state object is created with the desired changes. This immutability ensures predictability and helps in tracking state changes, making debugging and testing easier.
