R UBY, R UBY, R UBY

Optional Syntax puts ‘Hello World’ puts(‘Hello World’) puts(‘Hello World’);

puts ‘Hello World’

puts(‘Hello World’)

puts(‘Hello World’);

Simple declarations x = 1

x = 1

Natural Programming x = [1,2,3] y = [4,5,6] x + y == [1,2,3,4,5,6]

x = [1,2,3]

y = [4,5,6]

x + y == [1,2,3,4,5,6]

Everything is an object “ Hello World”.upcase [5,3,4,1,6].sort 10.times { }

“ Hello World”.upcase

[5,3,4,1,6].sort

10.times { }

Blocks 10.times do |i| puts i end 10.times { |i| puts i }

10.times do |i|

puts i

end

10.times { |i| puts i }
