phoenix enum filter
To filter a list using an enum in Elixir Phoenix, you can use the Enum.filter/2
function. This function takes two arguments: the list you want to filter and a function that defines the filtering condition.
Here's an example of how you can use Enum.filter/2
in Elixir Phoenix to filter a list:
list = [1, 2, 3, 4, 5]
filtered_list = Enum.filter(list, fn x -> x > 2 end)
In this example, the list
variable contains the original list [1, 2, 3, 4, 5]
. The Enum.filter/2
function is then used to filter the list based on the condition fn x -> x > 2 end
, which filters out any elements that are not greater than 2. The resulting filtered list is stored in the filtered_list
variable.
After executing this code, the value of filtered_list
will be [3, 4, 5]
, as those are the elements in the original list that satisfy the filtering condition.
I hope this helps! Let me know if you have any further questions.
