The code you showed works. However, we usually try to reduce the number of single use variables. So, the “Elixir way” of writing that code is

```
var1 = 
  123
  |> get_new_value(:something)
  |> get_new_value(:something2)

```

Furthermore, if it was the last statement in a function, then we would drop the var1 like this:

```
def my_fun do
  # ...
  123
   |> get_new_value(:something)
   |> get_new_value(:something2)
end

```
