Why should I use immutable objects in programming?

Why should I use immutable objects in programming?

Using immutable objects can lead to safer and more predictable code. They help avoid side effects and make debugging easier.

Can you explain how they improve performance?

Immutable objects can enhance performance by enabling optimizations like caching and sharing, as they don't change state.

What are some examples of immutable objects?

Common examples include strings in Java and tuples in Python. They cannot be modified after creation.

Are there any downsides to using them?

One downside is that they can lead to increased memory usage since new objects are created instead of modifying existing ones.

How do I implement immutable objects in my code?

You can implement them by using final classes in Java or using libraries like Immutable.js in JavaScript.
