What is the map function in Haskell?

Can you explain what the map function does in Haskell?

Sure! The map function in Haskell applies a given function to each element of a list, returning a new list with the results.

Can you give me an example of how to use map?

Of course! For instance, if you have a list of numbers [1, 2, 3] and you want to double each number, you can use map (*2) [1, 2, 3], which will return [2, 4, 6].

What types of functions can I use with map?

You can use any function that takes a single argument and returns a value. It can be a built-in function or a custom one you define.

Is map lazy in Haskell?

Yes, map is lazy in Haskell, meaning it only evaluates elements as they are needed, which can improve performance.
