1 00:00:00,870 --> 00:00:03,450 Before we usually write a function like this 2 00:00:32,270 --> 00:00:32,750 now. 3 00:00:32,800 --> 00:00:33,230 Yes. 4 00:00:33,270 --> 00:00:35,060 This weekend thanks to this 5 00:00:53,980 --> 00:00:56,910 we do not need to focus on. 6 00:00:57,140 --> 00:00:59,650 Instead we use cornerstone. 7 00:00:59,650 --> 00:01:00,760 And then you call 8 00:01:03,770 --> 00:01:07,340 and on the air or hear 9 00:01:38,300 --> 00:01:40,630 if the function only have one line of code. 10 00:01:40,730 --> 00:01:44,570 In return we can also simplify 11 00:01:52,080 --> 00:01:55,040 Renteria to breakfast and through the return 12 00:01:58,680 --> 00:01:59,690 and change days. 13 00:01:59,680 --> 00:02:08,220 Only one parameter here we can also delete the Brexit but make sure that if you have two a perimeter 14 00:02:08,250 --> 00:02:10,650 you will have to add a Brexit. 15 00:02:10,710 --> 00:02:13,650 So since these only have one perimeter. 16 00:02:13,890 --> 00:02:17,940 So now we can only just use the name here without a Brexit.
