This check has a base priority of high and works with any version of Elixir.


Because if and unless are macros, the preferred style is to not use parentheses around conditions.

# preferred

if valid?(username) do
  # ...

# NOT preferred

if( valid?(username) ) do
  # ...

Like all Readability issues, this one is not a technical concern. But you can improve the odds of others reading and liking your code by making it easier to follow.
