How can I avoid mutation in JavaScript?

To avoid mutation in JavaScript, you can use techniques like immutability, functional programming, and libraries like Immutable.js.

Can you explain immutability in more detail?

Immutability means that once a data structure is created, it cannot be changed. Instead of modifying it, you create a new version with the desired changes.

What are some libraries that help with immutability?

Some popular libraries for immutability include Immutable.js, Immer, and Ramda. They provide tools to work with immutable data structures.

Are there any performance considerations when using immutable data?

Yes, while immutability can lead to cleaner code, it may introduce overhead due to the creation of new objects. However, libraries like Immer optimize this process.
