What are the best practices in functional programming?

Some best practices include using pure functions, avoiding side effects, and leveraging higher-order functions.

Can you explain why pure functions are important?

Pure functions are important because they always produce the same output for the same input, making code easier to test and reason about.

What are higher-order functions?

Higher-order functions are functions that can take other functions as arguments or return them as results, enabling powerful abstractions.

How can I avoid side effects in my code?

You can avoid side effects by ensuring that your functions do not modify any external state and only rely on their input parameters.
