Block Parameters

Blocks receive parameters and can make local calculations for each yielded value.

block_parameters.rb

numbers = [2, 4, 6]
multiplier = 

numbers.each do |number|
  product = number * multiplier
  puts "#{number}x#{multiplier}=#{product}"
end

numbers = [2, 4, 6]
multiplier = 

numbers.each do |number|
  product = number * multiplier
  puts "#{number}x#{multiplier}=#{product}"
end

numbers = [2, 4, 6]
multiplier = 

numbers.each do |number|
  product = number * multiplier
  puts "#{number}x#{multiplier}=#{product}"
end
