43
Returns true if list contains the given value.
Examples
iex> Mandrake.List.contains(3, [1, 2, 3, 4, 5])
true
Returns a new list without the given item.
Examples
iex> delete_4 = Mandrake.List.delete(4)
...> delete_4.([1, 2, 4, 3, 4, 5, 6])
[1, 2, 3, 5, 6]
Returns a new list without the given item.
Examples
iex> Mandrake.List.delete([1, 2, 4, 3, 4, 5, 6], 4)

Returns the difference of the 2 lists.
Examples
iex> Mandrake.List.difference([1, 2, 3], [2])
[1, 3]
Returns true if all elements in a list are equal.
Examples
iex> Mandrake.List.equals([7, 7, 7])
true
Returns the first item of a list that returns true for the function.
Examples
iex> printHello = Mandrake.List.first(fn x -> Kernel.rem(x, 2) == 0 end, [2, 4, 5, 7])
2
Returns a new list after applying the given function to each element of the list.
Examples
iex> Mandrake.List.for_each(fn x -> x + 1 end, [1, 2, 3])
[2, 3, 4]
Returns a new list starting from the given value or nil.
Examples
iex> Mandrake.List.from(43, [4, 7, 43, 6, 3, 7])
[43, 6, 3, 7]
Returns the intersection of the 2 lists.
Examples
iex> Mandrake.List.intersection([1,2,3,4], [7,6,5,4,3])
[3, 4]
Returns the last item of a list that returns true for the function.
Examples
iex> Mandrake.List.last(fn x -> Kernel.rem(x, 2) == 0 end, [2, 4, 5, 7, 8, 9])
8
Returns a list containing the given value.
Examples
iex> Mandrake.List.of("Example")
["Example"]
Returns a list of 2 lists. The first contains the elements that satisfy the function, other elements are in the second.
Examples
iex> even = Mandrake.List.partition(fn item -> Kernel.rem(item, 2) == 0 end)
...> even.([4, 7, 43, 6, 3, 7])
[[4, 6], [7, 43, 3, 7]]
Returns a list of 2 lists. The first contains the elements that satisfy the function, other elements are in the second.
Examples
iex> Mandrake.List.partition(fn item -> Kernel.rem(item, 2) == 0 end, [4, 7, 43, 6, 3, 7])
[[4, 6], [7, 43, 3, 7]]
Returns a list composed by the value of the properties for the given key from items in the given list.
Examples
iex> pluck_example = Mandrake.List.pluck(:example)
...> pluck_example.([%{ name: "Doe" }, %{ example: "first", name: "John" }, %{ example: "second" }])
[ "first", "second" ]
