How do you check for the type of variable in Elixir

Question

In Elixir how do you check for type such as in Python:

>>> a = \"test\"
>>> type(a)

>>> b =10
>>> type(b         


        

Answer 1

Another approach is to use pattern matching. Say you're using Timex, which uses a %DateTime{} struct, and you want to see if an element is one. You can find a match using pattern matching in the method.

def is_a_datetime?(%DateTime{}) do
  true
end

def is_a_datetime?(_) do
  false
end
