method chaining

day6homework3.rb

# Chain at least 5 method calls to an object. Reduce this operation one chain at a time.

# Don't just use the methods below, make up your own chain and try to see if you can do something fun with Ruby like in the example.

# Example:

# puts "start".reverse.slice(0,2).concat("uth").capitalize
# # => Truth
# Because:

# puts "start".reverse
# #=> trats

# puts "start".reverse.slice(0,2)
# #=> tr

# puts "start".reverse.slice(0,2).concat("uth")
# #=> truth

# puts "start".reverse.slice(0,2).concat("uth").capitalize
# #=> Truth
# At any given point in the chain, there is an evaluation that then receives the next method call.

puts "racecar".upcase

puts "racecar".upcase.slice(0..3)

puts "racecar".upcase.slice(0..3).reverse

puts "racecar".upcase.slice(0..3).reverse.concat(" RAC")

puts "racecar".upcase.slice(0..3).reverse.concat(" RAC").reverse
