What are the best practices for working with immutable data?

When working with immutable data, it's important to ensure that you create copies of data structures instead of modifying them directly. This helps maintain data integrity and makes debugging easier.

Can you give me an example of how to implement this in JavaScript?

Sure! In JavaScript, you can use the spread operator to create a new object or array. For example, to update a property in an object, you can do: const newObj = {...oldObj, newProp: newValue};.

What are the benefits of using immutable data?

The benefits include easier debugging, improved performance in certain scenarios, and safer concurrent programming since immutable data cannot be changed.

Are there any libraries that can help with immutable data?

Yes, libraries like Immutable.js and Immer can help manage immutable data structures in JavaScript, making it easier to work with.
