🤔 Presence and Blank Helpers​

ActiveSupport extends objects with blank?, present?, and presence for concise nil/empty checks. Use these to guard values or provide fallbacks instead of verbose conditionals.

[].blank?          # => true
"Hello".present?   # => true
name = params[:name].presence || "Guest"
# If params[:name] is blank or nil, name => "Guest"
