Which library is commonly used to handle immutable state in a more readable and less verbose way than traditional methods?

Immutable.js is a commonly used library in React applications to handle immutable state in a more readable and less verbose way than traditional methods. It provides data structures like Map and List that enforce immutability. React State refers to the built-in state management in React but doesn't directly address immutability. Redux is a state management library but doesn't inherently focus on immutability. JavaScript alone doesn't provide specific tools for handling immutable state.
