elixir enum map

To map over a list in Elixir using the Enum.map/2 function, you can provide a function as the second argument to Enum.map/2. This function will be applied to each element of the list, and the result of each application will be collected into a new list.

Here's an example of how to use Enum.map/2 in Elixir:

list = [1, 2, 3, 4, 5]

new_list = Enum.map(list, fn(x) -> x * 2 end)

IO.inspect(new_list)

In this example, we have a list [1, 2, 3, 4, 5]. We use Enum.map/2 to apply the anonymous function fn(x) -> x * 2 end to each element of the list. This function multiplies each element by 2. The result is a new list [2, 4, 6, 8, 10], which is then printed using IO.inspect.

You can replace the anonymous function in the example with any other function that you want to apply to each element of the list. This allows you to perform custom transformations on the elements of the list.

I hope this helps! Let me know if you have any further questions.
