Delete multiple elements from a list

I think you are looking for this

# Example with static values
iex> [1, 2, 3, 4, 5] -- [1, 2]
[3, 4, 5]

# Example with Enum.drop/2, with multiple values
iex> Enum.drop([1, 2, 3, 4, 5], 2)
[3, 4, 5]
iex> Enum.drop([1, 2, 3, 4, 5], -2)
[1, 2, 3]
iex> Enum.drop([1, 2, 3, 4, 5], 20)
[]
iex> Enum.drop([1, 2, 3, 4, 5], -20)
[]

You can use List.delete/2 only can delete one at time and Enum.drop/2 can delete multiple depend how you use it.

If you want to remove elements based on some arbitrary condition, you can use Enum.reject/2, and provide the reject condition as an argument.

iex(1)> Enum.reject([1,2,3,4,5], fn x -> x in [1,2] end)
[3, 4, 5]
