you can also use pattern matching
Enum.find_index(list, fn %{id: ^id} -> true; _ -> false end)
you could also use filter to just remove the item
Enum.filter(list, fn %{id: ^id} -> false; _ -> true end)

Pinning, so it will match the already bound value instead of rebinding. However in this case I think that it would be more readable to do:
Enum.find(list, fn elem -> elem.id == id end)

As @hauleth said, you can pin the variable. So if this is wrapped into a function
def remove_alert(alerts, id) do
Enum.filter(alerts, fn %{id: ^id} -> true; _ false end)
end
You can match on the id variable in the parent scope, without the ^, id just gets assigned to whatever the id of the alert is in the fn scope.
