• end - Recommended for empty blocks, simple guards, and cleaner syntax
• {} - Useful for multi-line blocks with many statements

}

while i < 5
end

j = 0
while j < 5

  end
end

Using end Keyword

Mixed Usage

You can freely mix both styles in the same codebase:

# Empty function - use end
def placeholder end

# Function with body - use end
def process_data(data)
  validate(data)
  transform(data)
  save(data)
end

# Empty class - use end
class EmptyMarker end

# Class with methods - use end
class Service
  def init end

  def process
    fetch_data()
  end
end

# Control flow - use end for simple guards
if user.is_admin()
end

if user.is_valid()
  authorize(user)
end
