Can you explain what functional programming is?
Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state or mutable data.
What does immutability mean in this context?
Immutability means that once a data structure is created, it cannot be changed. Instead of modifying it, you create new versions of the data.
Why is immutability important in functional programming?
Immutability helps to avoid side effects, making code easier to understand, test, and maintain. It also enables safer concurrent programming.
Can you give an example of immutable data structures?
Sure! In languages like JavaScript, you can use libraries like Immutable.js to create immutable lists and maps that cannot be altered after creation.
