#ElixirLang has really useful optional parameters that can be passed to the "for" comprehension. For example, filtering the data on the fly.

list = [1, 1, 4, 6, 6, 8]

for x <- list, x > 5, uniq: true do
x + 1
end

# Result: [7, 9]

Don't sleep on the #ElixirLang Kernel module. Imported by default, Kernel provides us with a plethora of utilities. One of them is the "then" function that allows for piping of functions and effects that would otherwise not work in a pipeline.

$user_input = " HELLO " cleaned_text = user_input |> String.trim() |> String.downcase() |> then(fn text -> "clean: #{text}" end) # Result: "clean: hello"$
