# Declare an array of strings (like many languages, 
# single quotes are *not* interpolated)
properties = [ 'object oriented', 'duck typed', 'productive', 'fun']

# Call the Each function with a code block.
# Name each parameter "property" and output it
# "puts" is like printf - it will *put* a *s*tring to the screen
properties.each { | property | puts "Ruby is #{property}." }

# Note: irb output after properties.each is content of properties
