What are the best libraries for working with immutable collections in JavaScript?

Some of the best libraries for immutable collections in JavaScript include Immutable.js, Immer, and Mori. They provide efficient data structures and help manage state immutably.

Can you explain how Immutable.js works?

Immutable.js provides persistent immutable data structures, meaning that when you modify a collection, it returns a new version of that collection without altering the original. This helps in maintaining state in applications.

What are the advantages of using immutable collections?

Using immutable collections can lead to easier debugging, improved performance through structural sharing, and safer concurrent programming since data cannot be changed unexpectedly.

Are there any downsides to using these libraries?

Yes, some downsides include a steeper learning curve, potential performance overhead for small applications, and the need to adapt your coding style to work with immutable patterns.
