Immutable.js vs Immer

Developers should learn and use Immutable meets developers should learn and use immer when building applications that require immutable state updates, such as those using redux, react's usestate/usereducer, or other state management libraries, to avoid manual deep cloning and reduce boilerplate code. Here's our take.

Immutable.js

Nice Pick

Developers should learn and use Immutable

Pros

• js when building applications that require predictable state management, such as in React or Redux-based projects, to avoid unintended side effects and improve performance through structural sharing
• Related to: javascript, react

Cons

• Specific tradeoffs depend on your use case

Immer

Developers should learn and use Immer when building applications that require immutable state updates, such as those using Redux, React's useState/useReducer, or other state management libraries, to avoid manual deep cloning and reduce boilerplate code

Pros

• It is particularly useful in scenarios involving nested state objects or arrays, where direct mutations can lead to bugs, and it helps enforce predictable state changes in frameworks like React by ensuring immutability without the cognitive overhead of spread operators or Object
• Related to: redux, react

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Immutable.js if: You want js when building applications that require predictable state management, such as in react or redux-based projects, to avoid unintended side effects and improve performance through structural sharing and can live with specific tradeoffs depend on your use case.

Use Immer if: You prioritize it is particularly useful in scenarios involving nested state objects or arrays, where direct mutations can lead to bugs, and it helps enforce predictable state changes in frameworks like react by ensuring immutability without the cognitive overhead of spread operators or object over what Immutable.js offers.

The Bottom Line

Immutable.js wins

Developers should learn and use Immutable
