What are immutable objects in functional programming?
Immutable objects are objects whose state cannot be modified after they are created. This concept is fundamental in functional programming.
Why are immutable objects important?
They help avoid side effects, making code easier to understand and debug. They also enable safer concurrent programming.
Can you give me an example of an immutable object?
Sure! In JavaScript, you can use Object.freeze()
to create an immutable object. For example: const obj = Object.freeze({ name: 'Alice' });
.
How do immutable objects affect performance?
While they can introduce overhead due to the need to create new objects instead of modifying existing ones, they often lead to more predictable and maintainable code.
