 Libraries such as Immutable.js provide persistent immutable data structures. These are collections that, once created, are never changed. Any modifications to the collection return a new collection that shares as much of the structure with the original as possible, minimizing unnecessary copying. Libraries such as Immutable.js provide persistent immutable data structures.

 +<note>**Object.freeze** only makes the object itself immutable, not any nested objects. You would have to recursively freeze nested objects to achieve deep immutability. **Immutable.js**, on the other hand, provides deep immutability out of the box.</note>

 +<note>
 +**Object.freeze** can be slow, especially if used recursively on large objects. **Immutable.js** is optimized for performance and can handle large data structures efficiently.
