=== Higher-Order Functions === Elixir supports higher-order functions, which are functions that can take other functions as arguments or return functions as results. These functions enable powerful abstractions and functional programming paradigms. Let's see an example: ```elixir numbers = [1, 2, 3] multiply_by_two = fn x -> x * 2 end result = Enum.map(numbers, multiply_by_two) ``` In this example, we define an anonymous function `multiply_by_two` and use it as an argument to the `Enum.map` function. `Enum.map` applies the given function to each element in the list `numbers` and returns a new list with the results. The `result` variable will contain the list `[2, 4, 6]`.
