Splat Arguments

The splat operator gathers extra positional arguments into an array.

splat_arguments.rb

def total(*numbers)
  numbers.sum
end

extra = 
values = [2, 3, extra]
result = total(*values)

puts "values=#{values.join(",")}"
puts "count=#{values.length}"
puts "total=#{result}"

def total(*numbers)
  numbers.sum
end

extra = 
values = [2, 3, extra]
result = total(*values)

puts "values=#{values.join(",")}"
puts "count=#{values.length}"
puts "total=#{result}"

def total(*numbers)
  numbers.sum
end

extra = 
values = [2, 3, extra]
result = total(*values)

puts "values=#{values.join(",")}"
puts "count=#{values.length}"
puts "total=#{result}"

splat argument `*args` captures any number of positional values passed to a method.
