What is functional programming and how do arrays fit into it?

What is functional programming and how does it relate to arrays?

Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions. Arrays are often used in functional programming to store collections of data that can be processed using functions.

Can you give me an example of using arrays in functional programming?

Sure! In functional programming, you might use the map function to apply a transformation to each element in an array. For example, if you have an array of numbers, you can use map to create a new array with each number doubled.

What are some benefits of using functional programming with arrays?

Some benefits include improved code readability, easier debugging, and the ability to leverage higher-order functions for more concise and expressive code.

Are there any downsides to functional programming with arrays?

Yes, some downsides can include performance overhead due to immutability and the potential for increased memory usage, especially with large datasets.
