Immutable.js vs Object.freeze

Developers should learn and use Immutable meets developers should use object. 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

Object.freeze

Developers should use Object

Pros

• freeze when they need to enforce immutability for objects, such as in functional programming paradigms, configuration objects, or constants that should not be modified at runtime
• Related to: javascript, immutability

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Immutable.js is a library while Object.freeze is a concept. We picked Immutable.js based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Immutable.js wins

Based on overall popularity. Immutable.js is more widely used, but Object.freeze excels in its own space.
