Array of CONSTANTS
Raw
array_of_constants.rb
# Lets say we need to have a list of all our states
# we could do it like this
ON = 'on'
OFF = 'off'
CLOSED = 'closed'
STATES = [ON, OFF, CLOSED]
# but adding a new state means adding it in 2 places
# versus
STATES = [
ON = 'on',
OFF = 'off',
CLOSED = 'closed',
]
# here we only need to add it once
