+# Lamba or Anonymous Functions
+
+## Create an anonymous function and bind it to a variable
+
+### Simple one
+
+```elixir
+iex> func = fn -> IO.puts("Hello") end
+#Function<21.126501267/0 in :erl_eval.expr/5>
+iex> func.()
+Hello
+:ok
+```
+
+### One with arguments
+
+```elixir
+iex> func = fn t -> IO.puts(t) end
+#Function<7.126501267/1 in :erl_eval.expr/5>
+iex> func.("Hello")
+Hello
+:ok
+```
+
+Another solution is the `&` operator used as syntastic sugar
+
+```elixir
+iex> func = &(&1 + &2)
+&:erlang.+/2
+iex> func.(2, 2)
+4
+```
