1
00:00:00,360 --> 00:00:03,900
Here's one more task, which requires a little bit of thinking.

2
00:00:04,290 --> 00:00:10,320
And as you can see, we must try to function, which can convert the time input given in 12 hours format

3
00:00:10,320 --> 00:00:11,970
to 24 hours format.

4
00:00:12,240 --> 00:00:14,040
And here we have use cases.

5
00:00:14,310 --> 00:00:18,450
This is why it is easier for us to check if we covered everything correctly.

6
00:00:18,750 --> 00:00:20,640
So let's try to create this function.

7
00:00:20,640 --> 00:00:24,900
And once again, this is not a function that you can solve in 30 seconds.

8
00:00:25,080 --> 00:00:27,870
So you can take your time and think about it a little bit.

9
00:00:31,360 --> 00:00:37,430
So let's create here, convert to 24 hour format, and we're getting hit time text.

10
00:00:37,940 --> 00:00:43,270
And actually what they want to do here first, I want to convert it to lowercase because actually here

11
00:00:43,270 --> 00:00:48,040
we will get AM and PM, and we want to be sure that they are lowercase.

12
00:00:48,370 --> 00:00:51,220
This is why here we can try time text lower.

13
00:00:51,550 --> 00:00:55,210
And here we want to call time text to lowercase.

14
00:00:55,540 --> 00:00:59,290
The second thing that I want to do is get hours and minutes separately.

15
00:00:59,440 --> 00:01:06,670
So what I want to write here is time text lower split and we want to split it by column because actually

16
00:01:06,670 --> 00:01:13,030
we have Colin in every single case and on the left we have ours and on the right we have minutes.

17
00:01:13,270 --> 00:01:17,820
And actually, here, I want to make it a structured an assignment here directly.

18
00:01:17,830 --> 00:01:21,490
I want to get first of all hours and secondly minutes.

19
00:01:21,760 --> 00:01:24,490
In this case, we're creating two local variables.

20
00:01:24,790 --> 00:01:30,100
If you don't want to write like this, you can name it with some temporary variable and then just read

21
00:01:30,100 --> 00:01:33,040
this temporary variable that hours and minutes.

22
00:01:33,340 --> 00:01:35,320
But here we come to difficult stuff.

23
00:01:35,560 --> 00:01:41,650
As you can see, sometimes we have just a single digit and sometimes we have two digits, but also we

24
00:01:41,650 --> 00:01:43,970
have a case where we have zero at the beginning.

25
00:01:44,170 --> 00:01:49,840
And here we also have one more case that we need to cover if we have here 12 hours.

26
00:01:50,020 --> 00:01:52,420
Then we must convert it to zero zero.

27
00:01:52,600 --> 00:01:55,180
This is why I want to write exactly this logic.

28
00:01:55,190 --> 00:02:02,710
So if time ticks lower dot and with and actually end with is a really nice function in JavaScript,

29
00:02:02,710 --> 00:02:05,590
which has shaken the toast string you send in with something.

30
00:02:05,800 --> 00:02:11,770
And here we can check for AM because actually we know that here we have 12 a.m. and it means that we

31
00:02:11,770 --> 00:02:13,510
must convert it to two zeros.

32
00:02:13,810 --> 00:02:16,930
This is why here I want to write hours equals.

33
00:02:17,140 --> 00:02:23,260
And here we are checking if our hours equals 12 and 12 as Austrian, because here we are, split in

34
00:02:23,260 --> 00:02:26,470
Austria and then we want here to get zero.

35
00:02:26,710 --> 00:02:28,990
In neither case, where get in here hours?

36
00:02:29,260 --> 00:02:33,220
And as you can see, first of all, I wrote here a single zero and not two zeros.

37
00:02:33,400 --> 00:02:34,750
And this is also important.

38
00:02:35,020 --> 00:02:40,930
And here I just directly assigned ours, which actually means we covered this logic to get a single

39
00:02:40,930 --> 00:02:41,320
zero.

40
00:02:41,560 --> 00:02:44,800
And in all other cases, we just get whatever we get.

41
00:02:45,040 --> 00:02:49,300
If it is five baguette and five if it is zero one, we will get zero one.

42
00:02:49,600 --> 00:02:51,500
So recovered our AM case.

43
00:02:51,540 --> 00:02:53,350
Now I want to cover PM Case.

44
00:02:53,380 --> 00:02:58,720
This is way here we can write owls and even may be elusive because we want to check for PM.

45
00:02:59,020 --> 00:03:02,470
And here we can write time, text, lower dot and ways.

46
00:03:02,620 --> 00:03:04,450
And here we get getting our PM.

47
00:03:04,810 --> 00:03:07,630
And in this case, we want to apply different logic.

48
00:03:07,720 --> 00:03:14,530
We want to sign here hours and we want to check if our hours equals 12th because this is again another

49
00:03:14,530 --> 00:03:14,980
case.

50
00:03:15,130 --> 00:03:22,810
In this case, we want to apply here hours or we want to write history in and inside plus hours plus

51
00:03:22,810 --> 00:03:23,260
12.

52
00:03:23,710 --> 00:03:29,060
But this code is doing a toll, as you can see here, I wrote plus hours what it does.

53
00:03:29,110 --> 00:03:31,480
Actually, we're getting our hours as a stream.

54
00:03:31,690 --> 00:03:35,230
So let's say that we're getting here 12 now, if I will, right here.

55
00:03:35,230 --> 00:03:37,620
Plus, at the beginning, we're getting here directly.

56
00:03:37,660 --> 00:03:41,500
No from a stream, which actually means we're converging this two number.

57
00:03:41,710 --> 00:03:43,640
And then we make +12.

58
00:03:43,660 --> 00:03:44,410
Why is that?

59
00:03:44,590 --> 00:03:49,540
Because let's say here where checking PM, for example, this case with zero one.

60
00:03:49,840 --> 00:03:50,500
And here we are.

61
00:03:50,500 --> 00:03:56,380
Chicken, OK, hours equals 12 now and then we want to make zero one plus 12.

62
00:03:56,560 --> 00:03:58,240
Let's check the South how it will be.

63
00:03:58,390 --> 00:04:00,280
So we're getting here zero one.

64
00:04:00,430 --> 00:04:02,410
And actually it is converted to one.

65
00:04:02,560 --> 00:04:08,280
And now after this, we're getting +12 and we're getting to 10, which actually means by adding 12,

66
00:04:08,410 --> 00:04:11,110
we're converting it to the correct PM time.

67
00:04:11,350 --> 00:04:15,910
And if we have 12 pm like this, then we simply leave it like 12.

68
00:04:16,060 --> 00:04:20,170
So actually here we could write 12 over could just take our hours.

69
00:04:20,410 --> 00:04:24,260
So what I want to do now, I want to check what we're getting inside hours.

70
00:04:24,310 --> 00:04:28,930
So here I want to console.log our convert to 24 hour format.

71
00:04:29,200 --> 00:04:32,440
And here is our time text and our hours.

72
00:04:32,710 --> 00:04:36,610
And now I want to copy all these cases and just run them.

73
00:04:36,760 --> 00:04:39,430
In this case, we can check that they're working correctly.

74
00:04:39,700 --> 00:04:43,420
I'm not allowed in the page and where I get an assignment to constant variable.

75
00:04:43,690 --> 00:04:46,720
And as you can see here, we're trying to override ours.

76
00:04:46,870 --> 00:04:48,250
And of course, it's forbidden.

77
00:04:48,490 --> 00:04:51,460
This is where whoever must write, Let, let's check this out.

78
00:04:51,700 --> 00:04:58,300
I am delighted and we are getting 412 zero four five five 12 12 zero one 13.

79
00:04:58,390 --> 00:05:05,470
Here we have PM 11 to three and 10 22, which actually means our logic for hours is correct.

80
00:05:05,770 --> 00:05:09,520
After this, we must add a leading zero in this whole cases.

81
00:05:09,610 --> 00:05:15,280
And as you can see, sometimes we don't need it and sometimes we must edit and we can easily solve it

82
00:05:15,280 --> 00:05:17,530
with one more plain JavaScript function.

83
00:05:17,740 --> 00:05:20,740
We can write here hours dot pads tired.

84
00:05:21,040 --> 00:05:23,200
And here we can provide to zero.

85
00:05:23,350 --> 00:05:28,990
And what it does is you can see here it pads the current screen with another screen multiple times,

86
00:05:28,990 --> 00:05:29,560
if needed.

87
00:05:29,980 --> 00:05:34,900
Which actually means here we're providing tool, which means we will have two symbols and here we have

88
00:05:34,900 --> 00:05:39,700
zero, which actually means if we don't have a symbol there, then we will put zero inside.

89
00:05:39,850 --> 00:05:45,700
And actually now I want to copy this part and just put inside our console.log to check if it's working.

90
00:05:46,000 --> 00:05:49,510
I am reloading the page and as you can see now, we're getting the correct time.

91
00:05:49,690 --> 00:05:54,100
So here we have two zero zero five and then all our correct numbers.

92
00:05:54,370 --> 00:05:58,150
Now we must implement our minutes and actually it is much easier.

93
00:05:58,390 --> 00:06:04,180
First of all, just to remind you, inside minutes, we'll also have P, M and M, and we must get rid

94
00:06:04,180 --> 00:06:04,480
of it.

95
00:06:04,810 --> 00:06:08,470
This is where we can write here directly means dots lies.

96
00:06:08,740 --> 00:06:11,080
And here we are using zero minus two.

97
00:06:11,290 --> 00:06:16,510
In this case, we will get rid of two symbols AM or PM and we will get just minutes here.

98
00:06:16,720 --> 00:06:22,240
And after this, I want to use pets tired just like we did previously, and here will be also two and

99
00:06:22,240 --> 00:06:22,630
zero.

100
00:06:22,810 --> 00:06:28,300
In this case, we will check, okay, if we have here eight, then we must get here zero eight and if

101
00:06:28,300 --> 00:06:31,240
we will have here two digits, then it is totally fine.

102
00:06:31,690 --> 00:06:34,780
Now we can just remove this console.log, but don't need it anymore.

103
00:06:34,960 --> 00:06:38,800
And actually, here in every single case, I want to write console.log.

104
00:06:39,310 --> 00:06:41,020
This is why let's change this now.

105
00:06:41,020 --> 00:06:44,290
I want to write here console.log, then open it.

106
00:06:44,410 --> 00:06:45,880
And here we have convert.

107
00:06:46,120 --> 00:06:46,990
And let's close.

108
00:06:46,990 --> 00:06:47,710
It was break it.

109
00:06:47,950 --> 00:06:49,510
Now we have all our cases.

110
00:06:49,510 --> 00:06:55,000
Let's check them out, aim to load in the page and we're getting our time and it is looking totally

111
00:06:55,000 --> 00:06:55,870
fine actually.

112
00:06:55,870 --> 00:07:01,300
Here, for example, we have minute zero zero three three five two five zero eight and so on.

113
00:07:01,540 --> 00:07:05,080
But the problem is that we forgot to put a colon between them.

114
00:07:05,350 --> 00:07:10,060
This is where human must write plus and between them just put a strain with the colon.

115
00:07:10,390 --> 00:07:14,290
And as you can see now, we get a nice time in 24 hours format.

116
00:07:14,560 --> 00:07:19,810
And actually, from my point of view, this is difficult to solve this task in five or ten minutes.

117
00:07:20,050 --> 00:07:26,020
You really need to sit there like maybe 15 minutes or half of an hour to check different cases, how

118
00:07:26,020 --> 00:07:27,700
you want to solve it and so on.

119
00:07:28,000 --> 00:07:33,790
So this is a nice task to check how you can convert different things between them with different logic,

120
00:07:34,000 --> 00:07:37,330
but it is not something that you can solve in one or two minutes.
