If i want to break our loop at specific condition then it is same as other languages .
In Ruby continue doesn't work , in this there is equivalent keyword i.e next

class Number
  def looping(d)
    while(d!=50)
     puts d
     d = d + 1  // doesn't support d++ 
    end
  end
 def brk(d)
    while(d > 20)
      d  = d - 1
      if d == 60
        next
      end  
      puts d    
    end
  end
end
b = Number.new
b.looping(1)
b.brk(70)

Output :

b.looping(1) // in this i use break keyword at d == 50 , so at 49 it exit the loop
