What is immutability?
Immutability in React and ReduxImmutability can be a confusing topic, and it appears everywhere in React, Redux, and JavaScript in general.You may have encountered errors where your React components do not re-render, even though you know you have changed the props, and someone says, "You should be making immutable state updates." Maybe you or one of your teammates regularly writes reducers in Redux that mutate the state, and we have to constantly correct them (the reducers, or our teammates 😄).It's complicated. It can be very subtle, especially if you're not sure what to look for. And honestly, if you're not sure why it's important, it's hard to care.
